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.

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.

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.

"mdadm --monitor --oneshot" can be used to get a warning

This patch add a systemd service and timer which can
be enabled with
systemctl enable mdmonitor-oneshot.service

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.

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: [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.
