#       "Block fixes for 4.19-rc6
#     
#        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)"

#       xen/blkfront: correct purging of persistent grants
#       Revert "xen/blkfront: When purging persistent grants, keep them in the buffer"
#       blk-mq: I/O and timer unplugs are inverted in blktrace
#       bcache: add separate workqueue for journal_write to avoid deadlock
#       xen/blkfront: When purging persistent grants, keep them in the buffer
#       block: fix deadline elevator drain for zoned block devices
#       blk-mq: Allow blocking queue tag iter callbacks
#       nvme: properly propagate errors in nvme_mpath_init
