io_uring: move timeout opcodes and handling into its own file Signed-off-by: Jens Axboe <axboe@kernel.dk>
2022-05-25 08:57:27 -06:00
io_uring: move cancelation into its own file This also helps cleanup the io_uring.h cancel parts, as we can make things static in the cancel.c file, mostly. Signed-off-by: Jens Axboe <axboe@kernel.dk>

io_uring: protect cq_timeouts with timeout_lock Read cq_timeouts in io_flush_timeouts() only after taking the timeout_lock, as it's protected by it. There are many places where we also grab ->completion_lock, but for instance io_timeout_fn() doesn't and still modifies cq_timeouts.

io_uring: revise completion_lock locking io_kill_timeouts() doesn't post any events but queues everything to task_work. Locking there is needed for protecting linked requests traversing, we should grab completion_lock directly instead of using io_cq_[un]lock helpers. Same goes for __io_req_find_next_prep().
