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)

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.

this affects cases where the file system is resized
independently, and then the lvresize command is used

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.

Subject: [PATCH 3/4] lvresize: fail early if mounted LV was renamed
If a mounted LV is renamed, then fs resizing utilities will fail,
so detect this condition and fail the command before any changes
are made.
(cherry picked from commit 5374a44c57127cdd832a675545c1d2bbf0b3751a)

Subject: [PATCH 4/4] udev: import previous results of blkid when in suspended
state
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.
