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: introduce locking helpers for CQE posting spin_lock(&ctx->completion_lock); /* post CQEs */ io_commit_cqring(ctx); spin_unlock(&ctx->completion_lock); io_cqring_ev_posted(ctx); We have many places repeating this sequence, and the three function unlock section is not perfect from the maintainance perspective and also makes it harder to add new locking/sync trick. Introduce two helpers. io_cq_lock(), which is simple and only grabs ->completion_lock, and io_cq_unlock_post() encapsulating the three call section.

io_uring: introduce locking helpers for CQE posting spin_lock(&ctx->completion_lock); /* post CQEs */ io_commit_cqring(ctx); spin_unlock(&ctx->completion_lock); io_cqring_ev_posted(ctx); We have many places repeating this sequence, and the three function unlock section is not perfect from the maintainance perspective and also makes it harder to add new locking/sync trick. Introduce two helpers. io_cq_lock(), which is simple and only grabs ->completion_lock, and io_cq_unlock_post() encapsulating the three call section.
