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.
v3: sent wrong set in v2, re-sending right one
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
