Merge tag 'io_uring-6.17-20250822' of git://git.kernel.dk/linux

Pull io_uring fixes from Jens Axboe:
 "Just two small fixes - one that fixes inconsistent ->async_data vs
  REQ_F_ASYNC_DATA handling in futex, and a followup that just ensures
  that if other opcode handlers mess this up, it won't cause any issues"

* tag 'io_uring-6.17-20250822' of git://git.kernel.dk/linux:
  io_uring: clear ->async_data as part of normal init
  io_uring/futex: ensure io_futex_wait() cleans up properly on failure
