From ed334e35e9e951f5524b39a8483ac7f802bfea0b Mon Sep 17 00:00:00 2001

Subject: [PATCH 11/21] device_id: nvme devices may use alternate wwids
Device quirks may cause sysfs wwid file to change what it
displays, from a bogus eui... string to an nvme... string.
The old wwid may be saved in system.devices, so recognizing
the device requires finding the old value from libnvme.
After matching the old bogus value using libnvme, system.devices
is updated with the current sysfs wwid value.
(cherry picked from commit d952358636887348c390784a8ca5efb87b26784f)

Subject: [PATCH 14/21] thin: deactivate converted volume early
Deactivate converted volume to pool early, so the conversion
exits early and does not leave some already created metadata
volumes that needed manual cleanup by user after command
aborted its conversion operation when the converted volume
was actually in-use (i.e. when user tried to convert
a mounted LV into a thin-pool, 2 extra volumes needed removal).

Subject: [PATCH 17/21] lv_manip: check fs resize is supported before LV
extension
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This avoids a situation where we would extend an LV and then we would
not do anything to the FS on it because the FS info check failed for some
reason, like the type was not supported (e.g. swap) or we could not resize
the FS unless being in some supported state (e.g. XFS to be mounted for
the xfs_growfs to work).
Before this patch (LV resized, FS not resized):
❯ lvextend --fs resize -L+4M vg/swap
Size of logical volume vg/swap changed from 32.00 MiB (8 extents) to 36.00 MiB (9 extents).
File system extend is not supported (swap).
File system extend error.
Logical volume vg/swap successfully resized.
With this patch (LV not resized, FS not resized):
❯ lvextend --fs resize -L+4M vg/swap
File system extend is not supported (swap).

Subject: [PATCH 18/21] tests: adjust lvresize-xfs tests for recent lvextend
changes
Because now, we are doing the fsinfo check before extending an LV and if
that check fails, we do not proceed to the LV extension itself and the
lvextend command bails out immediatelly.

Fix regression introduced with commit:
964012fdb924076e9ab97fabe00e759ddbf7c3bd
that effectively disabled memory locking before suspending volumes.
From merging/testing there remained wrong condition
as we really want to check for 0 memory reservation value
for both checked settings.
