Pull fsnotify updates from Jan Kara: - support for limited fanotify functionality for unpriviledged users - faster merging of fanotify events - a few smaller fsnotify improvements * tag 'fsnotify_for_v5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs: shmem: allow reporting fanotify events with file handles on tmpfs fs: introduce a wrapper uuid_to_fsid() fanotify_user: use upper_32_bits() to verify mask fanotify: support limited functionality for unprivileged users fanotify: configurable limits via sysfs fanotify: limit number of event merge attempts fsnotify: use hash table for faster events merge fanotify: mix event info and pid into merge key hash fanotify: reduce event objectid to 29-bit hash fsnotify: allow fsnotify_{peek,remove}_first_event with empty queue
