[RFC v2 0/4] fs: Add generic file system event notifications

[Beata Michalska <b.michalska-Sze3O3UU22JBDgjK7y7TUQ@public.gmane.org>]

Hi All,

This series is a follow-up of the RFC patchset for generic filesystem
events interface [1]. As there have been some rather significant changes
to the synchronization method being used, more extensive testing (stress
testing) has been performed (thus the delay).

Changes from v1:
	- Improved synchronization: switched to RCU accompanied with
	  ref counting mechanism
	- Limiting scope of supported event types along with default
	  event codes
	- Slightly modified configuration (event types followed by arguments
	  where required)
	- Updated documentation
	- Unified naming for netlink attributes
	- Updated netlink message format to include dev minor:major numbers
	  despite the filesystem type
	- Switched to single cmd id for messages
	- Removed the per-config-entry ids
