Patches 1-7 are cleanups mainly dealing with issue_flags conversions,
misundertsandings of the flags and of the tw state. It'd be great to have
even without even w/o the rest.

8-11 mandate ctx locking for task_work and finally removes the CQE
caches, instead we post directly into the CQ. Note that the cache is
used by multishot auxiliary completions.

Patches 12-14 are additional cleanups that were sent out in a separate
patchset before.

Beware, there are problems reported coming from ublk testing, which
may or may not be due to unrelated problems with for-next.


v2: Add Patch 3, which fixes deadlock due to nested locking
    introduced in v1

    Remove a fix, which was taken separately

    Pile up more cleanups (Patches 12-14)


Pavel Begunkov (14):
  io_uring/cmd: kill one issue_flags to tw conversion
  io_uring/cmd: fix tw <-> issue_flags conversion
  io_uring/cmd: make io_uring_cmd_done irq safe
  io_uring/cmd: introduce io_uring_cmd_complete
  ublk: don't hard code IO_URING_F_UNLOCKED
  nvme/io_uring: don't hard code IO_URING_F_UNLOCKED
  io_uring/rw: avoid punting to io-wq directly
  io_uring: force tw ctx locking
  io_uring: remove struct io_tw_state::locked
  io_uring: refactor io_fill_cqe_req_aux
  io_uring: get rid of intermediate aux cqe caches
  io_uring: remove current check from complete_post
  io_uring: refactor io_req_complete_post()
  io_uring: clean up io_lockdep_assert_cq_locked
