[GIT PULL] Block fixes for 4.17-rc2

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

I ended up sitting on this about a week longer than I wanted to,
since we were hashing out details with a timeout change. I've now
killed that patch, so we can flush the existing queue in due time.

This pull request contains:

- Fix for an old regression, where entering the queue can be disturbed
  by a signal to the process. This can cause spurious EIO. Fix from Alan
  Jenkins.

- cdrom information leak fix from Dan.

- Trivial helper for testing queue FUA from Dave Chinner, part of his
  O_DIRECT FUA series.

- Series of swim fixes from Finn that actually makes it work again.

- Loop O_DIRECT corruption fix, which caused data corruption in
  production for us. From me.

- BFQ crash fix from me.

- bcache maintainer update. Michael no longer has the time to do it,
  Coly has stepped up to serve as the new maintainer.

- blkcg locking fixes from Jiang Biao.

- Revert of a change from this merge window from Ming, that causes an
  issue on some hardware.

- Minor clarification doc addition from Linus Walleij.

Please pull!
