[PATCH for-next 0/3] further optimise drain

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

On top of "[PATCH 5.14 00/12] for-next optimisations"

The first two further optimise non-drain and rare-drain cases, so the
overhead of it on the hot/generic path is minimal. With those, I'm more
or less happy about draining.

3/3 inlines io_commit_cqring(). I didn't want to bloat the binary with
it before, but now the hot path is shrinked enough.

Pavel Begunkov (3):
  io_uring: switch !DRAIN fast path when possible
  io_uring: shove more drain bits out of hot path
  io_uring: optimise io_commit_cqring()
