Jens Axboe 561fb04a6a io_uring: replace workqueue usage with io-wq ... Drop various work-arounds we have for workqueues: - We no longer need the async_list for tracking sequential IO. - We don't have to maintain our own mm tracking/setting. - We don't need a separate workqueue for buffered writes. This didn't even work that well to begin with, as it was suboptimal for multiple buffered writers on multiple files. - We can properly cancel pending interruptible work. This fixes deadlocks with particularly socket IO, where we cannot cancel them when the io_uring is closed. Hence the ring will wait forever for these requests to complete, which may never happen. This is different from disk IO where we know requests will complete in a finite amount of time. - Due to being able to cancel work interruptible work that is already running, we can implement file table support for work. We need that for supporting system calls that add to a process file table. - It gets us one step closer to adding async support for any system call.
