The idea is to not pass struct sqe_submit as a separate entity,
but always use req->submit instead, so there will be less stuff to
care about.

Also, I've got steady +1% throughput improvement for nop tests.
Though, it's highly system-dependent, and I wouldn't count on it.

v2: fix use-after-free catched by Jens

v3: -EAGAIN, in case submission failed

Pavel Begunkov (3):
  io_uring: allocate io_kiocb upfront
  io_uring: Use submit info inlined into req
  io_uring: use inlined struct sqe_submit
