cbabdf2fca dmeventd: vdo plugin link lvm library
Since we fixed linking of proper version of 'libdevmapper' with
linking lvm2 plugin correctly - we already have correct function
available linked with internal lvm library.
So drop unneeded include of parsing function.

1da5fd8226 cov: inline _build_desc_write
Embed function into the code, since the function is actually
simpler written this as there are no memleak troubles

Avoid mem leaking hint on every loop continue and
allocate hint only when it's going to be added into list.

Switch to use 'dm_strncpy()' and validate sizes.

82e6b820b8 cov: check for NULL
Since we check for NULL pointers earlier we need
to be consistent across function - since the NULL
would applies across whole function.

When dropping 'mda' check - we are actually
already dereferencing it before - so it can't
be NULL at that places (and it's validated
before entering  _read_mda_header_and_metadata).

13c254fc05 fix dev_unset_last_byte after write error
dev_unset_last_byte() must be called while the fd is still valid.
After a write error, dev_unset_last_byte() must be called before
closing the dev and resetting the fd.

In the write error path, dev_unset_last_byte() was being called
after label_scan_invalidate() which meant that it would not unset
the last_byte values.

After a write error, dev_unset_last_byte() is now called in
dev_write_bytes() before label_scan_invalidate(), instead of by
the caller of dev_write_bytes().

In the common case of a successful write, the sequence is still:
dev_set_last_byte(); dev_write_bytes(); dev_unset_last_byte();

08f36dd093 lvextend: fix resizing volumes of different segtype
When resizing 2 volumes like  thin-pool and it's metadata and they
would be of a different type - command would be actually expecting
both LVs being of a same segtype - and would throw an error in
case they are different.

This patch fixes is by setting a new segtype from last segment of
2nd. extented device.

Also it fixes the possible 'percentage' extension setup that
might have been used for 'primary' volume - while the 'secondary'
LV always goes with direct size - as we do not support 'percentage'
setup for them

This affects maily usage of thin-pool where the extension of
thin-pool data size may also lead to extension of metadata size.

d1c5b3ae74 tests: avoid checking command result in cluster
When running cluster test with clvmd, the actual 'monitoring'
happens in cluster - so the 'already monitored' message
is also logged within clvmd code and the command cannot
see such effect.

clvmd was incapable to report this information back to command
so it cannot be displayed this way.

Add 'lvs -o+seg_monitor' validation which also works in clustered mode.

80b2de9e6a mirror: fix leg splitting
Enhance lv_info with lv_info_with_name_check.
This 'variant' not only check existance if UUID in DM table
but also compares its  DM name  whether it's matching expected LV name.
Otherwise activation may 'skip' activation with rename in case the
DM UUID already exists, just device is different name.

This change make fairly easier manipulation with i.e. detached mirror
leg which ATM is using same UUID - just the LV name have been changed.

Used code was not able to run 'activation' (and do a rename) and just
skipped the call. So the code used to do a workaround and 'tried'
to deactivate such LV firts - this however work only in non-clvmd case,
as cluster was not having the lock for deactivated LV.

With this extended lv_info code will run 'activation' and will
synchronize the name to match expected LV name.

Patch extends _lv_info() with new paramter 'with_name_check',
which is later translated into 'name_check' argument for
_info_run() which in case of name mismatch evaluates the
check as if device does not exists.

Such call is only used in one place _lv_activate() which then
let activation run.  All other invocation of _info() calls
are left intact.

TODO: fix mirror table manipulation (and raid)....
