[GIT PULL] vfs fixes

[Christian Brauner <brauner@kernel.org>]

Hey Linus,

/* Summary */
This contains a few simple vfs fixes for v6.3. There should be nothing
exciting in here:

* When allocating pages for a watch queue failed, we didn't return an
  error causing userspace to proceed even though all subsequent
  notifcations would be lost. Make sure to return an error.
* Fix a misformed tree entry for the idmapping maintainers entry.
* When setting file leases from an idmapped mount via generic_setlease()
  we need to take the idmapping into account otherwise taking a lease
  would fail from an idmapped mount.
* Remove two redundant assignments, one in splice code and the other in
  locks code, that static checkers complained about.

The watch queue and file lease fix should be backported.

/* Testing */
clang: Ubuntu clang version 15.0.2-1
gcc: gcc (Ubuntu 12.2.0-3ubuntu1) 12.2.0

All patches are based on v6.3-rc1 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.
