Merge tag 'fsnotify_for_v5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs

Browse Source 
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.
