Merge tag 'fsnotify_for_v5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs
Pull fsnotify updates from Jan Kara:
- fanotify fix for softlockups when there are many queued events
- performance improvement to reduce fsnotify overhead when not used
- Amir's implementation of fanotify events with names. With these you
can now efficiently monitor whole filesystem, eg to mirror changes to
another machine.
