  dm bufio: fix shrinker scans when (nr_to_scan < retain_target) (2017-12-08 10:54:25 -0500)

Please pull, thanks!

----------------------------------------------------------------
- Fix a particularly nasty DM core bug in a 4.15 refcount_t conversion.

- Fix various targets to dm_register_target after module __init
  resources created; otherwise racing lvm2 commands could result in a
  NULL pointer during initialization of associated DM kernel module.

- Fix regression in bio-based DM multipath queue_if_no_path handling.

- Fix DM bufio's shrinker to reclaim more than one buffer per scan.
