[PATCH v2 00/28] for-next patches

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

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.
