The first one adds checks {SQPOLL,IOPOLL} for open, close, etc.
And 3 others are just cleanups on top.
notes:
- it cures symptoms, but would be great what's with null-deref in [1/4]
- need to look whether epoll and sfr are affected by {SQ,IO}POLL
- it still allows statx with SQPOLL, because it has a bunchg of rules
for ignoring dirfd, e.g. when absolute path is specified.
Let's handle it separately.
Pavel Begunkov (4):
io_uring: fix open/close/statx with {SQ,IO}POLL
io_uring: do build_open_how() only once
io_uring: deduplicate io_openat{,2}_prep()
io_uring: move send/recv IOPOLL check into prep
