Jan,

This is the 5th revision of patch series to add support for filesystem
change monitoring to fanotify.

The complete work is available on fanotify_dirent-v5 branch [1] on github.

LTP tests by Matthew Bobrowski for FAN_REPORT_FID are available on
my LTP branch fanotify_fid [2]. A WIP test for dirent events is
available on my LTP branch fanotify_dirent [3].
Matthew Bobrowski is working on a proper test for dirent events and on
man pages for both FAN_REPORT_FID and dirent events (Thanks!).

The combined functionality of FAN_MARK_FILESYSTEM, FAN_REPORT_FID and
dirent modification events is demonstrated with a prototype of global
filesystem monitor based on inotify-tools [4].

Thanks,
Amir.

Changes since v4:
- Rebase on v5.0-rc1
- Address style review comments on v4
- info_len includes padding to info_hdr alignment
- handle caching of fsid correctly when inotify marks on object exist
- Report dirent events on subdirs only with FAN_ONDIR
- Report XXX_SELF events on directories only with FAN_ONDIR
- Do not merge dirent events on subdirs with dirent events on non subdirs
