From: Pavel Begunkov @ 2021-08-09 12:04 UTC (permalink / raw)
  To: Jens Axboe, io-uring

1,2 -- optimisation with kvmalloc()'ing file tables
4 -- optimise prep_rw() still touching inode with !REG fixed files
11 -- a small CQ waiting optimisation
20 -- put_task optimisation, saves atomics in many cases
23 -- helps req alloc sustainability, also needed for futures features

All others are cleanups, where 6-28 are resends.

v2: added patches 1-5

Pavel Begunkov (28):
  io_uring: use kvmalloc for fixed files
  io_uring: inline fixed part of io_file_get()
  io_uring: rename io_file_supports_async()
  io_uring: avoid touching inode in rw prep
  io_uring: clean io-wq callbacks
  io_uring: remove unnecessary PF_EXITING check
  io-wq: improve wq_list_add_tail()
  io_uring: refactor io_alloc_req
  io_uring: don't halt iopoll too early
  io_uring: add more locking annotations for submit
  io_uring: optimise io_cqring_wait() hot path
