[GIT PULL] Fsnotify changes for v5.15-rc1

[Jan Kara <jack@suse.cz>]

  Hello Linus,

  my vacation collides with the merge window which I expect to open next
week so I'm sending pull requests for the merge window early. Could you please
pull from

git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs.git fsnotify_for_v5.15-rc1

to get fsnotify speedups when notification actually isn't used and support
for identifying processes which caused fanotify events through pidfd
instead of normal pid.

Top of the tree is e43de7f0862b. The full shortlog is:

Amir Goldstein (4):
      fsnotify: replace igrab() with ihold() on attach connector
      fsnotify: count s_fsnotify_inode_refs for attached connectors
      fsnotify: count all objects with attached connectors
      fsnotify: optimize the case of no marks of any type

Matthew Bobrowski (5):
      kernel/pid.c: remove static qualifier from pidfd_create()
      kernel/pid.c: implement additional checks upon pidfd_create() parameters
      fanotify: minor cosmetic adjustments to fid labels
      fanotify: introduce a generic info record copying helper
      fanotify: add pidfd support to the fanotify API
