Patch adds extra check for lv_name not being NULL.
Test avoids unneeded strlen call for this case.
Otherwise there is no functional change as test would fail on
size_t comparation even for NULL lv_name (thus there is no risk
of NULL dereference when taking 'true' if branch.
Add test for NULL before passing uuid as src argument to memcpy.
As memcpy function is declared as function not accepting NULL.
Though we pass NULL only with zero length so this patch presents
no functional change to the code.
was lacking the (vgmem) pool. We now create that pool. There is at least one
more such VG (_dummy_vg) which is pool-less. I am not sure what is the right
way to go about this, but this is currently necessary to fix a segfault
introduced by using vgmem in the reporter in Dave's lvseg lvm2app patches.

Patch updates exec_cmd() and adds 3rd parameter with pointer for
status value, so caller might examine returned status code.
If the passed pointer is NULL, behavior is unmodified.
Patch allows to confinue with lvresize if the failure from fsadm check is
caused by mounted filesystem as many of filesystem resize tools do support
online filesystem resize. (originally user had to use flag '-n' to bypass
this filesystem check)
Simultaneous -a and --refresh is not valid.
poll+monitor are valid together with or without -ay* (but not with -an*)
No longer print polling results summary if no LVs in the VG were polled.
Makes clang happier as it covers all code paths and avoids NULL pointer
dereference through the 'com' pointer (which is NULL by default static
initialisation).
Reported by clang as: Argument with 'nonnull' attribute passed null
Reuse the result of the last strchr() call - make sure, 'st' point is not
null for the next strchr() call.
to lvm.conf in the activation section: 'snapshot_autoextend_threshold' and
'snapshot_autoextend_percent', that define how to handle automatic snapshot
extension. The former defines when the snapshot should be extended: when its
space usage exceeds this many percent. The latter defines how much extra space
should be allocated for the snapshot, in percent of its current size.
Reorder linked libraries so we better support --as-needed linker flag used
by some distributions (i.e. Gentoo).

Add ->target_name to segtype_handler to allow a more specific target
name to be returned based on the state of the segment.
Result of trying to merge a snapshot using a kernel that doesn't have
the snapshot-merge target:
Before:
# lvconvert --merge vg/snap
Can't expand LV lv: snapshot target support missing from kernel?
Failed to suspend origin lv
After:
# lvconvert --merge vg/snap
Can't process LV lv: snapshot-merge target support missing from kernel?
Failed to suspend origin lv
Unable to merge LV "snap" into it's origin.
re-add a physical volume that has gone missing previously, due to a transient
device failure, without re-initialising it.

may never complete.
If you convert from a linear to a mirror and then convert that
mirror back to linear /while/ the previous (up)convert is
taking place, the mirror polling process will never complete.
This is because the function that polls the mirror for
completion doesn't check if it is still polling a mirror and
the copy_percent that it gets back from the linear device is
certainly never 100%.
The fix is simply to check if the daemon is still looking at
a mirror device - if not, return PROGRESS_CHECK_FAILED.
The user sees the following output from the first (up)convert
if someone else sneaks in and does a down-convert shortly
after their convert:
[root@bp-01 ~]# lvconvert -m1 vg/lv
vg/lv: Converted: 43.4%
ABORTING: Mirror percentage check failed.
If pvmove crashed and metadata contains pvmove LV
but without miorrored segments, pvmove --abort
will not repair the situation (and finish wth success!).
Fix it by allowing metadata update if aborting
(thus removing pvmove LV) even if no moved LVs detected.
(Tested on real metadata provided by an lvm user:-)
This is not only undocumented but is is also in violation with --help
documentation.
Using --yes without --force is useful in pvcreate when it detects
old signature.
Ignore snapshots when performing mirror recovery beneath an origin.
Pass LCK_ORIGIN_ONLY flag around cluster.
Add suspend_lv_origin and resume_lv_origin using LCK_ORIGIN_ONLY.
Introduce --norestorefile to allow user to override the new requirement.
This can also be overridden with "devices/require_restorefile_with_uuid"
in lvm.conf -- however the default is 1.

An incorrect fix on July 13, 2010 for an annoyance has caused a regression.
The offending check-in was part of the 2.02.71 release of LVM. That
check-in caused any PVs specified on the command line to be ignored when
performing a mirror split.
This patch reverses the aforementioned check-in (solving the regressions)
and posits a new solution to the list reversal problem. The original
problem was that we would always take the lowest mimage LVs from a mirror
when performing a split, but what we really want is to take the highest
mimage LVs. This patch accomplishes that by working through the list in
reverse order - choosing the higher numbered mimages first. (This also
reduces the amount of processing necessary.)
