Subject: [PATCH] device_id: fix segfault verifying serial for non-pv
The recent change that verifies sys_serial system.devices entries
using the PVID did not exclude non-PV devices from being checked.
The verification code would attempt to use du->pvid which was null
for the non-PVs causing a segfault.
(cherry picked from commit 6613a61d3b5ce4d12a6fef79195eac34f30ef4da)

Subject: [PATCH 2/7] devices file: fail if --devicesfile filename doesn't

A typo of the filename after --devicesfile should result in a
command error rather than the command falling back to using no
devices file at all. Exception is vgcreate|pvcreate which
create a new devices file if the file name doesn't exist.

18722dfdf4d3 lvresize: restructure code
mistakenly changed the overprovisioning check from applying
to all lv_is_thin_type lvs to only lv_is_thin_pool lvs, so
it no longer applied when extending thin lvs. The result
was missing warning messages when extending thin lvs.

Subject: [PATCH 1/3] vgimportclone: fix importing PV without metadata
If one of the PVs in the VG does not hold metadata, then the
command would fail, thinking that PV was from a different VG.
Also add missing free on that error path.

From 3cfb00e5f7c720549100c5297be18600c9abf530 Mon Sep 17 00:00:00 2001

Subject: [PATCH 5/7] pvdisplay: restore --reportformat option
Fixes commit b8f4ec846 "display: ignore --reportformat"
by restoring the --reportformat option to pvdisplay.
Adding -C to pvdisplay turns the command into a reporting
command (like pvs, vgs, lvs) in which --reportformat can
be useful.
(cherry picked from commit db5277c97155632ce83e1125e348eda97c871968)

Subject: [PATCH] apply multipath_component_detection=0 to duplicate PV
handling
multipath_component_detection=0 has always applied to the filter-based
component detection. Also apply this setting to the duplicate-PV
handling which also eliminates multipath components (based on duplicate
PVs having the same wwid.)

Subject: [PATCH 2/4] lvresize: only resize crypt when fs resize is enabled
There were a couple of cases where lvresize, without --fs resize,
was resizing the crypt layer above the LV. Resizing the crypt
layer should only be done when fs resizing is enabled (even if the
fs is already small enough due to being independently reduced.)
Also, check the size of the crypt device to see if it's already
been reduced independently, and skip the cryptsetup resize if
it's not needed.

Follow-up for e10f67e91728f1e576803df884049ecbd92874d0.
The commit e10f67e91728f1e576803df884049ecbd92874d0 tries to keep device
node symlinks even if the device is in the suspended state. However,
necessary properties that may previously obtained by the blkid command
were not imported at least in the .rules file. So, unless ID_FS_xyz
properties are imported by another earlier .rules file, the device node
symlinks are still lost when event is processed in the suspended state.
Let's explicitly import the necessary properties.
