[GIT PULL] vfs: misc updates

[Christian Brauner <brauner@kernel.org>]

Hey Linus,

/* Summary */
This contains a pile of various smaller fixes. Most of them aren't very
interesting so this just highlights things worth mentioning:

* Various filesystems contained the same little helper to convert from
  the mode of a dentry to the DT_* type of that dentry. They have now
  all been switched to rely on the generic fs_umode_to_dtype() helper.
  All custom helpers are removed.
  (Jeff)
* Fsnotify now reports ACCESS and MODIFY events for splice.
  (Chung-Chiang Cheng)
* After converting timerfd a long time ago to rely on
  wait_event_interruptible_*() apis, convert eventfd as well. This
  removes the complex open-coded wait code.
  (Wen Yang)
* Simplify sysctl registration for devpts, avoiding the declaration of
  two tables. Instead, just use a prefixed path with register_sysctl().
  (Luis)
* The setattr_should_drop_sgid() helper is now exported so NFS can
  use it. By switching NFS to this helper an NFS setgid inheritance bug
  is fixed.
  (me)

/* Testing */
clang: Ubuntu clang version 15.0.6
gcc: (Ubuntu 12.2.0-3ubuntu1) 12.2.0

All patches are based on 6.3-rc2 and have been sitting in linux-next.
No build failures or warnings were observed. All old and new tests in
fstests, selftests, and LTP pass without regressions.

/* Conflicts */
At the time of creating this PR no merge conflicts were reported from
linux-next and no merge conflicts showed up doing a test-merge with
current mainline.
