Compare also file size to detect changed config file
...
Clvmd detects modifed config file before it takes lv_lock.
If the config file is changed rapidly - the change was ignored within
a seocnd ranged. This patch adds also compare of file size.
So change like some flag for 0 to 1 would pass unnoticed - but
it's quick fix for failing test suite.
FIXME: Implement inotify solution.

First stab at making lvmetad-core threadsafe. The current design should allow
...
very reasonable amount of parallel access, although the hash tables may become
a point of contention under heavy loads. Nevertheless, there should be orders
of magnitude less contention on the hash table locks than we currently have on
block device scanning.
