Add the infrastructure to attach a mark to a super_block struct
and detach all attached marks when super block is destroyed.
This is going to be used by fanotify backend to setup super block
marks.

Send events to group if super block mark mask matches the event
and unless the same group has an ignore mask on the vfsmount or
the inode on which the event occurred.
Soon, fanotify backend is going to support super block marks and
fanotify backend only supports path type events.

Add another mark type flag FAN_MARK_FILESYSTEM for add/remove/flush
of super block mark type.
A super block watch gets all events on the filesystem, regardless of
the mount from which the mark was added, unless an ignore mask exists
on either the inode or the mount where the event was generated.
Only one of FAN_MARK_MOUNT and FAN_MARK_FILESYSTEM mark type flags
may be provided to fanotify_mark() or no mark type flag for inode mark.

Thanks for the patches! I've queued them up to my tree for the next merge
window (will publish them as soon as LTP tests are finished). I've just
fixed a typo in comment in patch 3 and added comments into holes in flags
space in fanotify.h header.
