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
