Merge tag 'io_uring-5.5-20191220' of git://git.kernel.dk/linux-block

Pull io_uring fixes from Jens Axboe:
 "Here's a set of fixes that should go into 5.5-rc3 for io_uring.

  This is bigger than I'd like it to be, mainly because we're fixing the
  case where an application reuses sqe data right after issue. This
  really must work, or it's confusing. With 5.5 we're flagging us as
  submit stable for the actual data, this must also be the case for
  SQEs.

  Honestly, I'd really like to add another series on top of this, since
  it cleans it up considerable and prevents any SQE reuse by design. I
  posted that here:

    https://lore.kernel.org/io-uring/20191220174742.7449-1-axboe@kernel.dk/T/#u

  and may still send it your way early next week once it's been looked
  at and had some more soak time (does pass all regression tests). With
  that series, we've unified the prep+issue handling, and only the prep
  phase even has access to the SQE.

  Anyway, outside of that, fixes in here for a few other issues that
  have been hit in testing or production"

* tag 'io_uring-5.5-20191220' of git://git.kernel.dk/linux-block:
