| 2019-04-18 | Rename completion helpers | Jens Axboe | |
| We have io_uring_get_sqe() on the submission side, yet the completion side is named _completion. Rename as follows: io_uring_get_completion() io_uring_peek_cqe() iO_uring_wait_completion() io_uring_wait_cqe() This better tells the user what the _get variant does by calling it _peek instead, and we move to using _cqe() as the postfix instead of _completion.

| 2019-04-17 | Add io_uring_cqe_seen() | Jens Axboe | |
| There's a failure case where an application gets a cqe entry, but the kernel can then overwrite it before the application is done reading it. This can happen since the io_uring_{get,wait}_completion() interface both returns a CQE pointer AND increments the ring index. If the kernel reuses this entry before the applications is done reading it, the contents may be corrupted. Remove the CQ head increment from the CQE retrieval, and put it into a separate helper, io_uring_cqe_seen(). The application must call this helper when it got a new CQE entry through one of the above calls, and it's now done reading it. Signed-off-by: Jens Axboe <axboe@kernel.dk> | |||
