[GIT PULL] Block fixes for 5.3-rc4

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

Here's a set of fixes that should go into this release. This pull
request contains:

- Revert of a bcache patch that caused an oops for some (Coly)

- ata rb532 unused warning fix (Gustavo)

- AoE kernel crash fix (He)

- Error handling fixup for blkdev_get() (Jan)

- libata read/write translation and SFF PIO fix (me)

- Use after free and error handling fix for O_DIRECT fragments. There's
  still a nowait + sync oddity in there, we'll nail that start next
  week. If all else fails, I'll queue a revert of the NOWAIT change. (me)

- Loop GFP_KERNEL -> GFP_NOIO deadlock fix (Mikulas)

- Two BFQ regression fixes that caused crashes (Paolo)

Please pull!
