      kernel: provide create_io_thread() helper · cc440e87
      Jens Axboe authored
      Provide a generic helper for setting up an io_uring worker. Returns a
      task_struct so that the caller can do whatever setup is needed, then call
      wake_up_new_task() to kick it into gear.
      
      Add a kernel_clone_args member, io_thread, which tells copy_process() to
      mark the task with PF_IO_WORKER.

      io_uring: reliably cancel linked timeouts · dd59a3d5
      Pavel Begunkov authored
      Linked timeouts are fired asynchronously (i.e. soft-irq), and use
      generic cancellation paths to do its stuff, including poking into io-wq.
      The problem is that it's racy to access tctx->io_wq, as
      io_uring_task_cancel() and others may be happening at this exact moment.
      Mark linked timeouts with REQ_F_INLIFGHT for now, making sure there are
      no timeouts before io-wq destraction.
