[GIT PULL] io_uring fixes for 6.16-rc1

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

Followup small batch of fixes for io_uring that should go into the
6.16-rc1 kernel. This pull request contains:

- Fix for a regression introduced in this merge window, where the 'id'
  passed to xa_find() for ifq lookup is uninitialized.

- Fix for zcrx release on registration failure. From 6.15, going to
  stable.

- Tweak for recv bundles, where msg_inq should be > 1 before being used
  to gate a retry event.

- Pavel doesnt want to be a maintainer anymore, remove him from the
  MAINTAINERS entry.

- Limit legacy kbuf registrations to 64k, which is the size of the
  buffer ID field anyway. Hence it's nonsensical to support more than
  that, and the only purpose that serves is to have syzbot trigger long
  exit delays for heavily configured debug kernels.

- Fix for the io_uring futex handling, which got broken for
  FUTEX2_PRIVATE by a generic futex commit adding private hashes.

Please pull!
