2020-03-02io_uring: remove io_prep_next_work()Pavel Begunkov
io-wq cares about IO_WQ_WORK_UNBOUND flag only while enqueueing, so it's useless setting it for a next req of a link. Thus, removed it from io_prep_linked_timeout(), and inline the function. Signed-off-by: Pavel Begunkov <asml.silence@gmail.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2020-03-02io_uring: remove extra nxt check after puntPavel Begunkov
After __io_queue_sqe() ended up in io_queue_async_work(), it's already known that there is no @nxt req, so skip the check and return from the function. Also, @nxt initialisation now can be done just before io_put_req_find_next(), as there is no jumping until it's checked.

2020-03-02io_uring: use poll driven retry for files that support itJens Axboe
Currently io_uring tries any request in a non-blocking manner, if it can, and then retries from a worker thread if we get -EAGAIN. Now that we have a new and fancy poll based retry backend, use that to retry requests if the file supports it. This means that, for example, an IORING_OP_RECVMSG on a socket no longer requires an async thread to complete the IO. If we get -EAGAIN reading from the socket in a non-blocking manner, we arm a poll handler for notification on when the socket becomes readable. When it does, the pending read is executed directly by the task again, through the io_uring task work handlers. Not only is this faster and more efficient, it also means we're not generating potentially tons of async threads that just sit and block, waiting for the IO to complete. The feature is marked with IORING_FEAT_FAST_POLL, meaning that async pollable IO is fast, and that poll<link>other_op is fast as well. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2020-03-02io_uring: mark requests that we can do poll async in io_op_defsJens Axboe
Add a pollin/pollout field to the request table, and have commands that we can safely poll for properly marked. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2020-03-02io_uring: add per-task callback handlerJens Axboe
For poll requests, it's not uncommon to link a read (or write) after the poll to execute immediately after the file is marked as ready. Since the poll completion is called inside the waitqueue wake up handler, we have to punt that linked request to async context. This slows down the processing, and actually means it's faster to not use a link for this use case. We also run into problems if the completion_lock is contended, as we're doing a different lock ordering than the issue side is. Hence we have to do trylock for completion, and if that fails, go async. Poll removal needs to go async as well, for the same reason. eventfd notification needs special case as well, to avoid stack blowing recursion or deadlocks. These are all deficiencies that were inherited from the aio poll implementation, but I think we can do better. When a poll completes, simply queue it up in the task poll list. When the task completes the list, we can run dependent links inline as well. This means we never have to go async, and we can remove a bunch of code associated with that, and optimizations to try and make that run faster. The diffstat speaks for itself.

2020-03-02io_uring: store io_kiocb in wait->privateJens Axboe

2020-03-02task_work_run: don't take ->pi_lock unconditionallyOleg Nesterov
As Peter pointed out, task_work() can avoid ->pi_lock and cmpxchg() if task->task_works == NULL && !PF_EXITING. And in fact the only reason why task_work_run() needs ->pi_lock is the possible race with task_work_cancel(), we can optimize this code and make the locking more clear.

2020-03-02io-wq: use BIT for ulong hashPavel Begunkov

2020-03-02io_uring: remove IO_WQ_WORK_CBPavel Begunkov
IO_WQ_WORK_CB is used only for linked timeouts, which will be armed before the work setup (i.e. mm, override creds, etc). The setup shouldn't take long, so it's ok to arm it a bit later and get rid of IO_WQ_WORK_CB. Make io-wq call work->func() only once, callbacks will handle the rest. i.e. the linked timeout handler will do the actual issue. And as a bonus, it removes an extra indirect call.

2020-03-02io-wq: remove io_wq_flush and IO_WQ_WORK_INTERNALPavel Begunkov
io_wq_flush() is buggy, during cancelation of a flush, the associated work may be passed to the caller's (i.e. io_uring) @match callback.
