Subject: [PATCH] libmultipath: fix disassemble status for
historical-service-time PS
The historical-service-time path selector prints out 2 path group status
arguments. This is the only path selector that uses the group status
arguments. All the others only have path status arguments.
disassemble_status() was expecting the number of group status arguments
to always be zero, causing it to fail at disassembling the status of
devices that use historical-service-time path selector. Now multipath
actually checks the number of group arguments, and skips them.

Subject: [PATCH] libmultipath: make helper function to trigger path uevents
Pull the code that checks if a path needs to trigger a uevent, and
triggers, out of trigger_paths_udev_change() and into a new function,
trigger_path_udev_change(). This function will be used separately by
a future patch. No functional changes.

Subject: [PATCH] multipathd: trigger udev change on path addition
When a multipath device is created for the first time, there is a window
where some path devices way be added to the multipath device, but never
claimed in udev. This can allow other device owners, like lvm, to think
they can use the device.
When a multipath device is first created, all the existing paths that
are not claimed by multipath have a uevent triggered so that they can
get claimed. After that, multipath assumes all future paths added to the
multipath device will have been claimed by multipath, since the device's
WWID is now in the wwids file. This doesn't work for any paths that
have already been processed by the multipath.rules udev rules before
the multipath device was created.
To close this window, when path device is added, and a matching
multipath device already exists, multipathd now checks if the device is
claimed by multipath, and if not, triggers a uevent to claim it.

Subject: [PATCH] multipathd: disallow changing to/from fpin marginal paths on
reconfig
Setting marginal_pathgroups to fpin causes two new threads to be created
when multipathd starts. Turning it on after multipathd starts up won't
cause the theads to start, and turing it off won't keep the threads from
working. So disallow changing marginal_pathgroups to/from "fpin" on
reconfigure.

Subject: [PATCH] libmultipath: fix printing native nvme multipath topology.
Since commit 2f05df4 ("libmultipath: use strbuf in print.c"), when
multipath prints the topology of native nvme devices, instead of
printing the multipath device information, it prints "w [G]:d s". This
is because nvme_style() switched from calling snprintf(), which supports
format specifiers, to append_strbuf_str(), which doesn't, while still
keeping the same string, "%%w [%%G]:%%d %%s". Remove the extra percent
signs, since they don't need to be escaped in append_strbuf_str().
Fixes: 2f05df4 ("libmultipath: use strbuf in print.c")
