8e5f7cf3dc Move lvmcache data structures behind an API (making the structures private to 
lvmcache.c). No functional change.

b93c1332d1 Move label_init up in code stack 
label_exit() is called destroy_toolcontext() and we are now
using standard dm_list function for destroy, we have to make sure
dm_list gets initialized properly.

94f88a4f14 Fix test for lv_snapshot_percent 
Do not check for PERCENT_MERGE_FAILED if the lv_snapshot_percent() failed.
(test for snap_percent would be testing uninitialized value).

33dea28e23 Use dm_snprintf and improve error handling

84fd8ea4bd Move done jump lower 
Since before 'goto done' is bufused zeroed, it would otherwise write 1
byte in front of buffer.

b63b775143 Add boundary test for number of mirror devs and logs 
As atoi may return negative value - test for both limits.
Test log_args for limits before calling alloca().
Code from dmeventd mirror plugin should probably share same code as
we have in mirrored.c.

1a39fa0073 Move close few lines 
Since the function dev_close() has code path, which really could close
file (for unlocked vg) and destroy dev handler, stay on safe side and move
the close few lines later, even our current use case shouldn't trigger
such scenario.

ab852ffe66 Disable partial activation for thin LVs and LVs with all missing segments 
Count number of error and existing areas and if there is no existing area
for the LV avoid its activation.

Always disable partial activatio for thin volumes.

For mirrors currently put in hack to let it pass with a special name
since current mirror code needs to activate such LV during some operations.

ca12090800 Thin read percent info from layered device 
Since we only need layered device - check for tpool device presence,
so user doesn't need to activate thin pool explicitely for percent info.

9b1fe5a062 Thin clear stacked message for thin pool 
Before removing thin pool LV always make sure, stacked message
for previous run are cleared - but allow to remove any
device that should have been created
(i.e. creation of snapshot failed - so the message for snapshot creation
may be replaced with delete message within unfinished transaction).

Also commit messages after lv remove - so free space is released in pool.

2258242f6c Thin use origin_only for thin pools as well 
Extend the usage of origin_only flag to allow resume of thin pool LV
(when it's active) to pass only the messages.

origin_only flag will skip detection of already resumed tree for thin_pool,
so we do not need to suspend the tree and we just send messages.

efc8ca105d Thin add support for origin_only suspend of thin volumes 
Pass in the origin_only flag also for thin volumes - but curently the flag
is not used to its best.

FIXME: achieve the state where only  thin volume snapshot origin is
suspended without its childrens -  let's explore whether this may
happen automatically inside libdm (might be generic for other targets).
So the code would not need to annotate the node for this.

78c3b21bfa Thin add messages only for activation tree 
Extend lv_activate_opts with bool flag to know for which purpose
dtree is created - and add message only for activation tree
(since that's the only place that may send them).

Extend validation check for thin snapshot creation and test whether
active snapshot origin is suspended before its snapshot is created
(useful in recover scenarios) -  in this case also detect, whether
transaction has been already completed and avoid such suspend check
failure in that case.

3c4be983d5 lv_info using -real layer only for origin_only LV 
If the origin_only flag is passed for non lv_is_origin LVs,
the extension is not added.

Thin volumes may also use origin_only flag.
