1-2 put some limits on the fixed file tables sizes, files and

3/3 adds compatibility checks for ->splice_fd_in, for all requests
buy rw and some others, see the patch message.

All based on 5.15 and merked stable, looks to me as the best way.

Pavel Begunkov (3):
  io_uring: limit fixed table size by RLIMIT_NOFILE
  io_uring: place fixed tables under memcg limits
  io_uring: add ->splice_fd_in checks

Applied - especially 3/3 will be a bit of a stable pain. Nothing difficult,
just needs attention for each version...
