[PATCH 0/4] clean early submission path

[Pavel Begunkov <asml.silence@gmail.com>]

This is mainly in preparation for future changes, but looks nice
by itself. The last patch fixes a mild vulnerability.

Pavel Begunkov (4):
  io_uring: simplify io_get_sqring
  io_uring: alloc req only after getting sqe
  io_uring: remove req init from io_get_req()
  io_uring: don't read user-shared sqe flags twice
