[GIT PULL] Block fixes for 4.19-rc6

[GIT PULL] Block fixes for 4.19-rc6

[Jens Axboe]

Hi Greg,

A set of fixes that should go into this release. This pull request
contains:

- A fix (hopefully) for the persistent grants for xen-blkfront. A
  previous fix from this series wasn't complete, hence reverted, and
  this one should hopefully be it. (Boris Ostrovsky)

- Fix for an elevator drain warning with SMR devices, which is triggered
  when you switch schedulers (Damien)

- bcache deadlock fix (Guoju Fang)

- Fix for the block unplug tracepoint, which has had the timer/explicit
  flag reverted since 4.11 (Ilya)

- Fix a regression in this series where the blk-mq timeout hook is
  invoked with the RCU read lock held, hence preventing it from blocking
  (Keith)

- NVMe pull from Christoph, with a single multipath fix (Susobhan Dey)

Please pull!
