[PATCHv8 0/8] dm-multipath: push back requests instead of queueing

[Hannes Reinecke <hare@suse.de>]

Hi Mike,

here's now version 8 of the patchset; after testing I found that
the contentious delay when queueing items to a workqueue is in
fact not required. So with that I seem to have addressed all
outstanding issues.

Hannes Reinecke (6):
  dm mpath: do not call pg_init when it is already running
  dm mpath: push back requests instead of queueing
  dm mpath: remove process_queued_ios()
  dm mpath: reduce memory pressure when requeuing
  dm mpath: remove map_io()
  dm-mpath: do not activate failed paths

Mike Snitzer (2):
  dm table: add dm_table_run_md_queue_async
  dm mpath: remove extra nesting in map function
