Subject: [PATCH 0/5] batch completion + freeing improvements

Different batching improvements, that's it.

Unfortunately, I don't have a decent SSD/setup at hand to
benchmark it properly.

p.s. if extra 32 pointers on stack would be a problem, I wanted for
long to put submit_state into ctx itself.

Pavel Begunkov (5):
  io_uring: move io_req_complete() definition
  io_uring: replace list with array for compl batch
  io_uring: batch free in batched completion
  tasks: add put_task_struct_many()
  io_uring: batch put_task_struct()
