Add test for NULL from dm_poll_create.
Reorder dm_pool_destroy() before file close and add label out:.
Avoid leaking file descriptor if the allocation fails.
Nicely hidden memory leak in outf macro error path.
This macro is using out_text() and does automagical return_0.
That would leak tag_buffer allocated memory.
As there was same code for tags output - create _out_tags() function.
Set vg to NULL after releasing it as the following memlock() test may
lead to goto for the second call of vg_release() with the already
released vg pointer.
Similar to 'get' property internal functions.
Add specific 'set' function for vg_mda_copies.

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)
A merged snapshot's DM device is made to use the "error" target as part
of lvm's transaction to merge a snapshot. This snapshot merge use-case
aside, any device using the error target shouldn't be scanned.
Based on review comments, rename a few fields in lvm_property_type.
In particular, change 'is_writeable' to 'is_settable', which is
more intuitive to the intent of the bitfield (a 'set' function
exists for this field/property). Also, remove the char array
for 'id' - unnecessary as we can just use the string passed in
to do the strcmp. Finally rename the union members from n_val
to 'integer' and 's_val' to 'string'.
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.
Problem:
When both legs of a mirrored log fail, neither the log nor the parent
mirror can proceed. The repair code must be careful to replace the
log with an error target before operating on the parent - otherwise,
the parent can get stuck trying to suspend because it can't push through
any writes. The steps to replace the log device with an error target
were incomplete and resulted in the replacement not happening at all!
The code originally had all the necessary logic to complete the
replacement task, but was pulled out in a effort to clean-up that
section of code, while fixing another bug:
<offending commit msg>
In addition, I added following three changes.
- Removed tmp_orphan_lvs handling procedure
It seems that _delete_lv() can handle detached_log_lv properly
without adding mirror legs in mirrored log to tmp_orphan_lvs.
Therefore, I removed the procedure.
- Removed vg_write()/vg_commit()
Metadata is saved by vg_write()/vg_commit() just after detached_log_lv
is handled. Therefore, I removed vg_write()/vg_commit().

I've reverted the "clean-up" changes associated with that fix, but not what
that commit was actually fixing.

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.
