Subject: [PATCH v2 0/4] forbid fix {SQ,IO}POLL

The first one adds checks {SQPOLL,IOPOLL}. IOPOLL check can be
moved in the common path later, or rethinked entirely, e.g.
not io_iopoll_req_issued()'ed for unsupported opcodes.

3 others are just cleanups on top.


v2: add IOPOLL to the whole bunch of opcodes in [1/4].
    dirty and effective.

Pavel Begunkov (4):
  io_uring: fix {SQ,IO}POLL with unsupported opcodes
  io_uring: do build_open_how() only once
  io_uring: deduplicate io_openat{,2}_prep()
  io_uring: move send/recv IOPOLL check into prep
