6789424259 Do not scan devices unnecessarily for reseting error counter
For reseting error counter use directly btree cached elements and do not
create whole dev_iterator.

6470c383b2 Skip unnecessary lock_vol() call after volume deactivation
Improve condition within lock_vol so we are not calling extra unlock
if the volume just has been deactivated.

Patch uses lck_type and replaces negative 'and' condition to more
readable 'or' condition.
Few missing strace traces added.

cbfb6504a8 Add exec_cmd paramater sync_needed
As sync_local_dev_names() cannot be called within activation context,
add new parametr which allows to select if the sync call is needed
before executing new command.

77e3610e1a Speedup consequent activation calls
Stop calling fs_unlock() from lv_de/activate().
Start using internal lvm fs cookie for dm_tree.
Stop directly calling dm_udev_wait() and
dm_tree_set/get_cookie() from activate code -
it's now called through fs_unlock() function.

Add lvm_do_fs_unlock()

Call fs_unlock() when unlocking vg where implicit unlock solves the
problem also for cluster - thus no extra command for clustering
environment is required - only lvm_do_fs_unlock() function is added
to call lvm's fs_unlock() while holding lvm_lock mutex in clvmd.

Add fs_unlock() also to set_lv() so the command waits until devices
are ready for regular open (i.e. wiping its begining).

Move fs_unlock() prototype to activation.h to keep fs.h private
in lib/activate dir and not expose other functions from this header.

a23f91ad2f Add internal fs cookie

7cbf6fa3a6 Change import_vg_from_buffer to use config_tree
Change function import_vg_from_buffer() to import_vg_from_config_tree().
Instead of creating config tree inside the function allow config tree to
be passed as parameter - usable later for caching.

39b2b95477 Remove check for existance of vg pointer

b00600c247 Remove const usage from destroy callbacks

a1cbc61c34 Add new dm_prepare_selinux_context fn to libdevmapper and use it throughout.
Detect existence of new SELinux selabel interface during configure.
Use new dm_prepare_selinux_context instead of dm_set_selinux_context.

We should set the SELinux context before the actual file system object creation.
The new dm_prepare_selinux_context function sets this using the selabel_lookup
fn in conjuction with the setfscreatecon fn. If selinux/label.h interface
(that should be a part of the selinux library) is not found during configure,
we fallback to the original matchpathcon function instead.

3415f08149 Fix scanning of VGs without in-PV mdas.
Set cmd->independent_metadata_areas if metadata/dirs or disk_areas in use.
- Identify and record this state.

Don't skip full scan when independent mdas are present even if memlock is set.
- Clusters and OOM aren't supported, so no problem doing the proper scans.

Avoid revalidating the label cache immediately after scanning.
- A simple optimisation.

Support scanning for a single VG in independent mdas.
- Not used by the fix but I left it in anyway as later patches might use it.

1e9221af45 Remove reset of vg->vgmem pointer as it is access of already release memory
This reset of vgmem pointer causes access of already released memory.
(_vg_make_handle allocates vg from vgmem pool itself - which is a bit tricky)

Interestingly this memory fault was missed by our test suite.
