Subject: [RHEL7.7 PATCH 01/24] Assemble: keep MD_DISK_FAILFAST and
MD_DISK_WRITEMOSTLY flag
Before updating superblock of slave disks, desired_state value
is set for the target state of the slave disks. But it forgets
to check MD_DISK_FAILFAST and MD_DISK_WRITEMOSTLY flags. Then
start_arrays() calls ADD_NEW_DISK ioctl-call and pass the state
without MD_DISK_FAILFAST and MD_DISK_WRITEMOSTLY.
Currenlty it does not generate any problem because kernel does not
care MD_DISK_FAILFAST or MD_DISK_WRITEMOSTLY flags.

PART-POLICY has been accepted in mdadm.conf since the same
time that POLICY was accepted, but it was never documented.
So add the missing documentation.
Also fix a bug which would have stopped it from working if
anyone had ever tried to use it.

Subject: [RHEL7.7 PATCH 03/24] policy: support devices with multiple paths.
As new releases of Linux some time change the name of
a path, some distros keep "legacy" names as well. This
is useful, but confuses mdadm which assumes each device has
precisely one path.
So change this assumption: allow a disk to have several
paths, and allow any to match when looking for a policy
which matches a disk.

Subject: [RHEL7.7 PATCH 04/24] mdcheck: add systemd unit files to run mdcheck.
Having the mdcheck script is not use if is never run.
This patch adds systemd unit files so that it can easily
be run on the first Sunday of each month for 6 hours,
then on every subsequent morning until the check is
finished.
The units still need to be enabled with
systemctl enable mdcheck_start.timer
The timer will only actually be started when an array
which might need it becomes active.

Subject: [PATCH 04/83] udev: adapt rules to systemd v247
New events have been added in kernel 4.14 ("bind" and "unbind").
Systemd maintainer suggests to modify "add|change" branches.
This patches implements their suggestions. There is no issue yet because
new event types are not used in md.
Please see systemd announcement for details[1].

Subject: [RHEL7.7 PATCH 05/24] Monitor: add system timer to run --oneshot
periodically
"mdadm --monitor --oneshot" can be used to get a warning
if there are any degraded arrays. It can be helpful to get
this warning periodically while the condition persists.
This patch add a systemd service and timer which can
be enabled with
systemctl enable mdmonitor-oneshot.service
and will then provide daily warnings.

Subject: [PATCH 05/83] Replace error prone signal() with sigaction()
Up to this date signal() was used which implementation could vary [1].
Sigaction() call is preferred. This commit introduces replacement
from signal() to sigaction() by the use of signal_s() wrapper.
Also remove redundant signal.h header includes.

Subject: [RHEL7.7 PATCH 06/24] imsm: update metadata correctly while raid10
double degradation
Mdmon calls end_migration() when map state changes from normal to
degraded. It is not valid because in raid 10 double degradation case
mdmon breaks checkpointing but array is still rebuilding.
In this case mdmon has to mark map as degraded and continues marking
recovery checkpoint in metadata. Migration can be finished only if newly
failed device is a rebuilding device.
Add catching double degraded to degraded transition. Migration is
finished but map state doesn't change, array is still degraded.
Update failed_disk_num correctly. If double degradation
happens rebuild will start on the lowest slot, but this variable points
to the first failed slot. If second fail happens while rebuild this
variable shouldn't be updated until rebuild is not finished.

With a chunk size of 16Meg and data drive count of 8,
this calculate can easily overflow the 'int' type that

So force it to use "long" instead.

Subject: [PATCH 11/83] mdadm: add map_num_s()
map_num() returns NULL if key is not defined. This patch adds
alternative, non NULL version for cases where NULL is not expected.
There are many printf() calls where map_num() is called on variable
without NULL verification. It works, even if NULL is passed because
gcc is able to ignore NULL argument quietly but the behavior is
undefined. For safety reasons such usages will use map_num_s() now.
It is a potential point of regression.

Subject: [RHEL7.7 PATCH 12/24] imsm: finish recovery when drive with rebuild
fails
Commit d7a1fda2769b ("imsm: update metadata correctly while raid10 double
degradation") resolves main Imsm double degradation problems but it
omits one case. Now metadata hangs in the rebuilding state if the drive
under rebuild is removed during recovery from double degradation.
The root cause of this problem is comparing new map_state with current
and if they both are degraded assuming that nothing new happens.
Don't rely on map states, just check if device is failed. If the drive
under rebuild fails then finish migration, in other cases update map
state only (second fail means that destination map state can't be normal).
To avoid problems with reassembling move end_migration (called after
double degradation successful recovery) after check if recovery really
finished, for details see (7ce057018 "imsm: fix: rebuild does not
continue after reboot").
Remove redundant code responsible for finishing rebuild process. Function
end_migration do exactly the same. Set last_checkpoint to 0, to prepare
it for the next rebuild.

Subject: [PATCH 012/125] mdadm/systemd: remove KillMode=none from service file
For mdadm's systemd configuration, current systemd KillMode is "none" in
following service files,
- mdadm-grow-continue@.service
- mdmon@.service
This "none" mode is strongly againsted by systemd developers (see man 5
systemd.kill for "KillMode=" section), and is considering to remove in
future systemd version.
As systemd developer explained in disuccsion, the systemd kill process
is,
1. send the signal specified by KillSignal= to the list of processes (if
any), TERM is the default
2. wait until either the target of process(es) exit or a timeout expires
3. if the timeout expires send the signal specified by FinalKillSignal=,
KILL is the default
For "control-group", all remaining processes will receive the SIGTERM
signal (by default) and if there are still processes after a period f
time, they will get the SIGKILL signal.
For "mixed", only the main process will receive the SIGTERM signal, and
if there are still processes after a period of time, all remaining
processes (including the main one) will receive the SIGKILL signal.
From the above comment, currently KillMode=control-group is a proper
kill mode. Since control-gropu is the default kill mode, the fix can be
simply removing KillMode=none line from the service file, then the
default mode will take effect.

Subject: [RHEL7.7 PATCH 13/24] imsm: fix reshape for >2TB drives
If reshape is performed on drives larger then 2 TB,
migration checkpoint area that is calculated exeeds 32-bit value.
This checkpoint area is a reserved space threated as backup
during reshape - at the end of the drive, right before metadata.
As a result - wrong space is used and the data that may exists there
is overwritten.
Adding additional field to migration record to track high order 32-bits
of pba of this area. Three other fields that may exceed 32-bit value
for large drives are added as well.

Subject: [PATCH 13/83] mdmon: Stop parsing duplicate options
Introduce new function is_duplicate_opt() to check if given option
was already used and prevent setting it again along with an error
message.
Move parsing above in_initrd() check to be able to detect --offroot
option duplicates.
Now help option is executed after parsing to prevent executing commands
like: 'mdmon --help --ndlksnlksajndfjksndafasj'.

Subject: [RHEL7.7 PATCH 15/24] Detail.c: do not skip first character when
calling xstrdup in Detail()
'Commit b9c9bd9bacaa ("Detail: ensure --export names are acceptable as
shell variables")' duplicates mdi->sys_name to sysdev string by,
char *sysdev = xstrdup(mdi->sys_name + 1);
which skips the first character of mdi->sys_name. Then when running
mdadm --detail <md device> --export, the output looks like,
MD_DEVICE_ev_sda2_ROLE=1
MD_DEVICE_ev_sda2_DEV=/dev/sda2
The first character of md device (between MD_DEVICE and _ROLE/_DEV)
is dropped. The expected output should be,
MD_DEVICE_dev_sda2_ROLE=1
MD_DEVICE_dev_sda2_DEV=/dev/sda2
This patch removes the '+ 1' from calling xstrdup() in Detail(), which
gets the dropped first character back.

Subject: [RHEL7.7 PATCH 16/24] Fix reshape for decreasing data offset
...when not changing the number of disks.
This patch needs context to explain. These are the relevant parts of
the original code (condensed and annotated):
if (dir > 0) {
/* Increase data offset (reshape backwards) */
if (data_offset < sd->data_offset + min) {
pr_err("--data-offset too small on %s\n",
dn);
goto release;
}
} else {
/* Decrease data offset (reshape forwards) */
if (data_offset < sd->data_offset - min) {
pr_err("--data-offset too small on %s\n",
dn);
goto release;
}
}
When this code is reached, mdadm has already decided on a reshape
direction. When increasing the data offset, the reshape runs backwards
(dir==1); when decreasing the data offset, the reshape runs forwards
(dir==-1).
The conditional within the backwards reshape is correct: the requested
offset must be larger than the old offset plus a minimum delta; thus the
reshape has room to work.
For the forwards reshape, the requested offset needs to be smaller than
the old offset minus a minimum delta; to do this correctly, the
comparison must be reversed.
Also update the error message.
Note: I have tested this change on a RAID 5 on Linux 4.18.0 and verified
that there were no errors from the kernel and that the device data
remained intact. I do not know if there are considerations for different
RAID levels.

Subject: [PATCH 16/83] Mdmonitor: Fix segfault
Mdadm with "--monitor" parameter requires md device
as an argument to be monitored. If given argument is
not a md device, error shall be returned. Previously
it was not checked and invalid argument caused
segmentation fault. This commit adds checking
that devices passed to mdmonitor are md devices.

Subject: [PATCH 18/83] Fix possible NULL ptr dereferences and memory leaks
In Assemble there was a NULL check for sra variable,
which effectively didn't stop the execution in every case.
That might have resulted in a NULL pointer dereference.
Also in super-ddf, mu variable was set to NULL for some condition,
and then immidiately dereferenced.
Additionally some memory wasn't freed as well.

Subject: [RHEL7.7 PATCH 18/24] mdmon: don't attempt to manage new arrays when
terminating
When mdmon gets a SIGTERM, it stops managing arrays that are clean. If
there is more that one array in the container and one of them is dirty
and the clean one is still present in mdstat, mdmon will treat it as a
new array and start managing it again. This leads to a cycle of
remove_old() / manage_new() calls for the clean array, until the other
one also becomes clean.
Prevent this by not calling manage_new() if sigterm is set. Also, remove
a check for sigterm in manage_new() because the condition will never be
true.

Subject: [RHEL7.7 PATCH 19/24] mdmon: wait for previous mdmon to exit during
takeover
Since the patch c76242c5("mdmon: get safe mode delay file descriptor
early"), safe_mode_dalay is set properly by initrd mdmon. But in some
cases with filesystem traffic since the very start of the system, it
might take a while to transit to clean state. Due to fact that new
mdmon does not wait for the old one to exit - it might happen that the
new one switches safe_mode_delay back to seconds, before old one exits.
As the result two mdmons are running concurrently on same array.
Wait for the old mdmon to exit by pinging it with SIGUSR1 signal, just
in case it is sleeping.

If array was stopped during reshape initialization,
there might be a "0" checkpoint recorded in metadata.
If array with such condition (reshape with position 0)
is passed to kernel - it will refuse to start such array.
Treat such array as normal during assemble, Grow_continue() will
reinitialize and start the reshape.

Subject: [PATCH 20/83] Revert "mdadm: fix coredump of mdadm --monitor -r"
This reverts commit 546047688e1c64638f462147c755b58119cabdc8.
The change from commit mdadm: fix coredump of mdadm
--monitor -r broke the printing of the return message when
passing -r to mdadm --manage, the removal of a device from
an array.
If the current code reverts this commit, both issues are
still fixed.
The original problem reported that the fix tried to address
was: The --monitor -r option requires a parameter,
otherwise a null pointer will be manipulated when
converting to integer data, and a core dump will appear.
The original problem was really fixed with:
60815698c0a Refactor parse_num and use it to parse optarg.
Which added a check for NULL in 'optarg' before moving it
to the 'increments' variable.
New issue: When trying to remove a device using the short
argument -r, instead of the long argument --remove, the
output is empty. The problem started when commit
546047688e1c was added.
Steps to Reproduce:
1. create/assemble /dev/md0 device
2. mdadm --manage /dev/md0 -r /dev/vdxx
Actual results:
Nothing, empty output, nothing happens, the device is still
connected to the array.
The output should have stated "mdadm: hot remove failed
for /dev/vdxx: Device or resource busy", if the device was
still active. Or it should remove the device and print
a message:
mdadm: set /dev/vdd faulty in /dev/md0
mdadm: hot removed /dev/vdd from /dev/md0
The following commit should be reverted as it breaks
mdadm --manage -r.

Subject: [RHEL7.7 PATCH 21/24] add missing units to --examine
Within the output of "mdadm --examine", there are three sizes reported
on adjacent lines. For example:
$ sudo mdadm --examine /dev/md3
[...]
Avail Dev Size : 17580545024 (8383.06 GiB 9001.24 GB)
Array Size : 17580417024 (16765.99 GiB 18002.35 GB)
Used Dev Size : 11720278016 (5588.66 GiB 6000.78 GB)
[...]
This can be confusing, since the first and third line are in 512-byte
sectors, and the second is in KiB.
Add units to avoid ambiguity.
(I don't particularly like the "KiB" notation, but it is at least
unambiguous.)

Subject: [RHEL7.7 PATCH 22/24] imsm: fix spare activation for old matrix
arrays
During spare activation get_extents() calculates metadata reserved space based
on smallest active RAID member or it will take the defaults. Since patch
611d9529("imsm: change reserved space to 4MB") default is extended. If array
was created prior that patch, reserved space is smaller. In case of matrix
RAID - spare is activated in each array one-by-one, so it is spare for first
activation, but treated as "active" during second one.
In case of adding spare drive to old matrix RAID with the size the same as
already existing member drive the routine will take the defaults during second
run and mdmon will refuse to rebuild second volume, claiming that the drive
does not have enough free space.
Add parameter to get_extents(), so the during spare activation reserved space
is always based on smallest active drive - even if given drive is already
active in some other array of matrix RAID.

Subject: [PATCH 22/83] mdadm/super1: restore commit 45a87c2f31335 to fix
clustered slot issue
Commit 9d67f6496c71 ("mdadm:check the nodes when operate clustered
array") modified assignment logic for st->nodes in write_bitmap1(),
which introduced bitmap slot issue:
load_super1 didn't set up supertype.nodes, which made spare disk only
have one slot info. Then it triggered kernel md_bitmap_load_sb to get
wrong bitmap slot data.
For fixing this issue, there are two methods:
1> revert the related code of commit 9d67f6496c71. and restore the code
from former commit 45a87c2f31335 ("super1: add more checks for
NodeNumUpdate option").
st->nodes value would be 0 & 1 under current code logic. i.e.
When adding a spare disk, there is no place to init st->nodes, and
the value is ZERO.
2> keep 9d67f6496c71, add additional ->nodes handling in load_super1(),
let load_super1 to set st->nodes when bitmap is BITMAP_MAJOR_CLUSTERED.
Under current mdadm code logic, load_super1 will be called many
times, any new code in load_super1 will cost mdadm running more time.
And more reason is I prefer as much as possible to limit clustered
code spreading in every corner.
So I used method <1> to fix this issue.
How to trigger:
dd if=/dev/zero bs=1M count=1 oflag=direct of=/dev/sda
dd if=/dev/zero bs=1M count=1 oflag=direct of=/dev/sdb
dd if=/dev/zero bs=1M count=1 oflag=direct of=/dev/sdc
mdadm -C /dev/md0 -b clustered -e 1.2 -n 2 -l mirror /dev/sda /dev/sdb
mdadm -a /dev/md0 /dev/sdc
mdadm /dev/md0 --fail /dev/sda
mdadm /dev/md0 --remove /dev/sda
mdadm -Ss
mdadm -A /dev/md0 /dev/sdb /dev/sdc
the output of current "mdadm -X /dev/sdc":
(there should be (by default) 4 slot info for correct output)
```
Filename : /dev/sdc
Magic : 6d746962
Version : 5
UUID : a74642f8:a6b1fba8:58e1f8db:cfe7b082
Events : 29
Events Cleared : 0

Chunksize : 64 MB

Write Mode : Normal
Sync Size : 306176 (299.00 MiB 313.52 MB)
Bitmap : 5 bits (chunks), 5 dirty (100.0%)
```
And mdadm later operations will trigger kernel output error message:
(triggered by "mdadm -A /dev/md0 /dev/sdb /dev/sdc")
```
kernel: md0: invalid bitmap file superblock: bad magic
kernel: md_bitmap_copy_from_slot can't get bitmap from slot 1

When passed size is smaller than chunk, mdadm rounds it to 0 but 0 there
means max available space.
Block it for every metadata. Remove the same check from imsm routine.

Subject: [PATCH 24/83] imsm: use same slot across container
Autolayout relies on drives order on super->disks list, but
it is not quaranted by readdir() in sysfs_read(). As a result
drive could be put in different slot in second volume.
Make it consistent by reffering to first volume, if exists.
Use enum imsm_status to unify error handling.

Subject: [PATCH 25/83] imsm: block changing slots during creation
If user specifies drives for array creation, then slot order across
volumes is not preserved.
Ideally, it should be checked in validate_geometry() but it is not
possible in current implementation (order is determined later).
Add verification in add_to_super_imsm_volume() and throw error if
mismatch is detected.
IMSM allows to use only same members within container.
This is not hardware dependency but metadata limitation.
Therefore, 09-imsm-overlap test is removed. Testing it is pointless.
After this patch, creation in this scenario is blocked. Offset
verification is covered in other tests.

Subject: [RHEL7.8 PATCH V2 25/47] mdmon: fix wrong array state when disk fails
during mdmon startup
If a member drive disappears and is set faulty by the kernel during
mdmon startup, after ss->load_container() but before manage_new(), mdmon
will try to readd the faulty drive to the array and start rebuilding.
Metadata on the active drive is updated, but the faulty drive is not
removed from the array and is left in a "blocked" state and any write
request to the array will block. If the faulty drive reappears in the
system e.g. after a reboot, the array will not assemble because metadata
on the drives will be incompatible (at least on imsm).
Fix this by adding a new option for sysfs_read(): "GET_DEVS_ALL". This
is an extension for the "GET_DEVS" option and causes all member devices
to be returned, even if the associated block device has been removed.
Use this option in manage_new() to include the faulty device on the
active_array's devices list. Mdmon will then properly remove the faulty
device from the array and update the metadata to reflect the degraded
state.

imsm_create_metadata_update_for_size_change() that returns u_size value

is always the size of imsm_update_size_change structure, check for
u_size is no longer needed.

Subject: [PATCH 29/83] Monitor: use devname as char array instead of pointer
Device name wasn't filled properly due to incorrect use of strcpy.
Strcpy was used twice. Firstly to fill devname with "/dev/md/"
and then to add chosen name. First strcpy result was overwritten by
second one (as a result <device_name> instead of "/dev/md/<device_name>"
was assigned). This commit changes this implementation to use snprintf
and devname with fixed size.

Subject: [PATCH 31/83] Makefile: Don't build static build with everything and
everything-test
Running the test suite requires building everything, but it seems to be
difficult to build the static version of mdadm now seeing there
is no readily available static udev library.
The test suite doesn't need the static binary so just don't build it
with the everything or everything-test targets.
Leave the mdadm.static and install-static targets in place in case
someone still has a use case for the static binary.

Subject: [RHEL7.8 PATCH V2 32/47] mdadm: add --no-devices to avoid component
devices detail information
When people assemble a md raid device with a large number of
component deivces (e.g. 1500 DASD disks), the raid device detail
information generated by 'mdadm --detail --export $devnode' is very
large. It is because the detail information contains information of
all the component disks (even the missing/failed ones).
In such condition, when udev-md-raid-arrays.rules is triggered and
internally calls "mdadm --detail --no-devices --export $devnode",
user may observe systemd error message ""invalid message length". It
is because the following on-stack raw message buffer in systemd code
is not big enough,
systemd/src/libudev/libudev-monitor.c
_public_ struct udev_device *udev_monito ...
struct ucred *cred;
union {
struct udev_monitor_netlink_header nlh;
char raw[8192];
} buf;
Even change size of raw[] from 8KB to larger size, it may still be not
enough for detail message of a md raid device with much larger number of
component devices.
To fix this problem, an extra option '--no-devices' is added (the
original idea is proposed by Neil Brown). When printing detailed
information of a md raid device, if '--no-devices' is specified, then
all component devices information will not be printed, then the output
message size can be restricted to a small number, even with the systemd
only has 8KB on-disk raw buffer, the md raid array udev rules can work
correctly without failure message.

Subject: [RHEL7.8 PATCH V2 33/47] udev: add --no-devices option for calling
'mdadm --detail'
When creating symlink of a md raid device, the detailed information of
component disks are unnecessary for rule udev-md-raid-arrays.rules. For
md raid devices with huge number of component disks (e.g. 1500 DASD
disks), the detail information of component devices can be very large
and exceed udev monitor's on-stack message buffer.
This patch adds '--no-devices' option when calling mdadm by,
IMPORT{program}="BINDIR/mdadm --detail --no-devices --export $devnode"
Now the detailed output won't include component disks information,
and the error message "invalid message length" reported by systemd can
be removed.

Subject: [RHEL7.8 PATCH V2 34/47] imsm: close removed drive fd.
When member drive fails, managemon prepares metadata update and adds
the drive to disk_mgmt_list with DISK_REMOVE flag. It fills only
minor and major. It is enough to recognize the device later.
Monitor thread while processing this update will remove the drive from
super only if it is a spare. It never removes failed member from
disks list. As a result, it still keeps opened descriptor to
non-existing device.
If removed drive is not a spare fill fd in disk_cfg structure
(prepared by managemon), monitor will close fd during freeing it.
Also set this drive fd to -1 in super to avoid double closing because
monitor will close the fd (if needed) while replacing removed drive
in array.

The test 07reshape-grow fails most of the time. But it succeeds around
1 in 5 times. When it does succeed, it causes the tests to die because
mdadm has segfaulted.
The segfault was caused by mdadm attempting to repoen a file

at mdadm.c:1510
The file descriptor was closed early in Grow_continue(). The noted commit
moved the close() call to close the fd above the fork which caused the
parent process to return with a closed fd.
This meant reshape_array() and Grow_continue() would return in the parent
with the fd forked. The fd would eventually be passed to reopen_mddev()
which returned an unhandled NULL from fd2devnm() which would then be
dereferenced in devnm2devid.
Fix this by moving the close() call below the fork. This appears to
fix the 07revert-grow test. While we're at it, switch to using
close_fd() to invalidate the file descriptor.

Not all struct superswitch implement a get_bad_blocks() function,

Subject: [PATCH 36/83] mdadm: Fix mdadm -r remove option regression
The commit noted below globally adds a parameter to the -r option but missed
the fact that -r is used for another purpose: --remove.
After that commit, a command such as:
mdadm /dev/md0 -r /dev/loop0
will do nothing seeing the device parameter will be consumed as a
argument to the -r option; thus, there will only be one device
seen one the command line, devs_found will only be 1 and nothing will
happen.
This caused the 01r5integ and 01raid6integ tests to hang indefinitely
as mdadm did not remove the failed device. With the device not removed,
it would not be readded. Then the loop waiting for the array status to
change would loop forever.
This commit was recently reverted, but the legitimate fix for the
monitor operations was still not fixed. So add specific monitor
short ops to re-fix the --monitor -r option.

Subject: [RHEL7.8 PATCH V2 36/47] mdadm: Introduce new array state 'broken'
for raid0/linear
Currently if a md raid0/linear array gets one or more members removed while
being mounted, kernel keeps showing state 'clean' in the 'array_state'
sysfs attribute. Despite udev signaling the member device is gone, 'mdadm'
cannot issue the STOP_ARRAY ioctl successfully, given the array is mounted.
Nothing else hints that something is wrong (except that the removed devices
don't show properly in the output of mdadm 'detail' command). There is no
other property to be checked, and if user is not performing reads/writes
to the array, even kernel log is quiet and doesn't give a clue about the
missing member.
This patch is the mdadm counterpart of kernel new array state 'broken'.
The 'broken' state mimics the state 'clean' in every aspect, being useful
only to distinguish if an array has some member missing. All necessary
paths in mdadm were changed to deal with 'broken' state, and in case the
tool runs in a kernel that is not updated, it'll work normally, i.e., it
doesn't require the 'broken' state in order to work.
Also, this patch changes the way the array state is showed in the 'detail'
command (for raid0/linear only) - now it takes the 'array_state' sysfs
attribute into account instead of only rely in the MD_SB_CLEAN flag.

The code path for metadata 0.90 calls a common routine
fname_from_uuid that uses metadata 1.2. The code expects member
swapuuid to be setup and usable. But it is only setup when using
metadata 1.2. Since the metadata 0.90 did not create swapuuid
and set it. The test (st->ss == &super1) ? 1 : st->ss->swapuuid
fails. The swapuuid is set at compile time based on byte order.
Any call based on metadata 0.90 and on big endian processors,
the --export uuid will be incorrect.

Subject: [RHEL7.8 PATCH V2 39/47] Init devlist as an array
devlist is an string. It will change to an array if there is disk that
is sbd disk. If one device is sbd, it runs devlist=().
This line code changes devlist from a string to an array. If there is
no sbd device, it can't run this line code. So it will still be a string.
The later codes need an array, rather than an string. So init devlist
as an array to fix this problem.

Subject: [PATCH 39/83] tests: fix raid0 tests for 0.90 metadata
Some of the test cases fail because raid0 creation fails with the error,
"0.90 metadata does not support layouts for RAID0" added by commit,
329dfc28debb. Fix some of the test cases by switching from raid0 to
linear level for 0.9 metadata where possible.

Subject: [RHEL7.8 PATCH V2 41/47] udev: allow for udev attribute reading bug.
There is a bug in udev (which will hopefully get fixed, but
we should allow for it anways).
When reading a sysfs attribute, it first reads the whole
value of the attribute, then reads again expecting to get
a read of 0 bytes, like you would with an ordinary file.
If the sysfs attribute changed between these two reads, it can
get a mixture of two values.
In particular, if it reads when 'array_state' is changing from
'clear' to 'inactive', it can find the value as "clear\nve".
This causes the test for "|clear|active" to fail, so systemd is allowed
to think that the array is ready - when it isn't.
So change the pattern to allow for this but adding a wildcard at
the end.
Also don't allow for an empty string - reading array_state will
never return an empty string - if it exists at all, it will be
non-empty.

Add functionality to continue if a test marked as broken fails.
To mark a test as broken, a file with the same name but with the suffix
'.broken' should exist. The first line in the file will be printed with
a KNOWN BROKEN message; the rest of the file can describe the how the
test is broken.
Also adds --skip-broken and --skip-always-broken to skip all the tests
that have a .broken file or to skip all tests whose .broken file's first
line contains the keyword always.

Subject: [RHEL7.8 PATCH V2 44/47] mdcheck: when mdcheck_start is enabled,
enable mdcheck_continue too.
mdcheck_continue continues a regular array scan that was started by
mdcheck_start.
mdcheck_start will ensure that mdcheck_continue is active.
Howver if you reboot after a check has started, but before it finishes,
then mdcheck_continue won't cause it to continue, because nothing
starts it on boot.
So add an install option for mdcheck_contine, and make sure it
gets enabled when mdcheck_start is enabled.

Subject: [PATCH 44/83] tests: Add broken files for all broken tests
Each broken file contains the rough frequency of brokeness as well
as a brief explanation of what happens when it breaks. Estimates
of failure rates are not statistically significant and can vary
run to run.
This is really just a view from my window. Tests were done on a
small VM with the default loop devices, not real hardware. We've
seen different kernel configurations can cause bugs to appear as well
(ie. different block schedulers). It may also be that different race
conditions will be seen on machines with different performance
characteristics.
These annotations were done with the kernel currently in md/md-next:

Subject: [PATCH 45/83] mdadm: Replace obsolete usleep with nanosleep
According to POSIX.1-2001, usleep is considered obsolete.
Replace it with a wrapper that uses nanosleep, as recommended in man.
Add handy macros for conversions between msec, usec and nsec.

Subject: [RHEL7.8 PATCH V2 45/47] mdcheck: use ${} to pass variable to mdcheck
$MDADM_CHECK_DURATION allows the value to be split on spaces.
${MDADM_CHECK_DURATION} avoids such splitting.
Making this change removes the need for double quoting when setting
the default Environment, and means that double quoting isn't needed
in the EnvironmentFile.

Subject: [PATCH 46/83] tests/00readonly: Run udevadm settle before setting ro
In some recent kernel versions, 00readonly fails with:
mdadm: failed to set readonly for /dev/md0: Device or resource busy
ERROR: array is not read-only!
This was traced down to a race condition with udev holding a reference
to the block device at the same time as trying to set it read only.
To fix this, call udevadm settle before setting the array read only.

Subject: [RHEL7.8 PATCH V2 47/47] super-intel: don't mark structs 'packed'
unnecessarily
super-intel marks a number of structures 'packed', but this
doesn't change the layout - they are already well organized.
This is a problem a gcc warns when code takes the address
of a field in a packet struct - as super-intel sometimes does.
So remove the marking where isn't needed.
Do ensure this does introduce a regression, add a compile-time
assertion that the size of the structure is exactly the value
it had before the 'packed' notation was removed.
Note that a couple of structure do need to be packed.
As the address of fields is never taken, that is safe.
