[PATCHSET 0/6] Various bug fixes

[Jens Axboe <axboe@kernel.dk>]

Hi,

A random bag of fixes and cleanups. In detail:

- Patch 1, defensive cleanup for a patch merged in this merge window.
  Not reachable, but it's confusing and should get cleaned up.

- Patch 2, spectre masking for file updates.

- Patch 3, defensive cleanup for the imu cache, using kvfree()
  consistently. Idea being that it'd be easy to mess this up in the
  future if caching changes.

- Patch 4, more defensive cleanups, just hardening ensuring that
  only >= 0 is passed in for bytes consumed for the kbuf path.

- Patch 5, actual fix for futex, where multiple partial wakeups would
  end up waking the same queue multiple times, rather than moving on
  to the next one.

- Patch 6, actual fix for ring resizing with CQE32/SQE128 and pending
  entries in the SQ or CQ rings.
