dm writecache: remove disabled code in memory_entry() (2018-10-22 10:59:52 -0400)
Please pull, thanks.

----------------------------------------------------------------
- Biggest change this cycle is to remove support for the legacy IO path
(.request_fn) from request-based DM. Jens has already started
preparing for complete removal of the legacy IO path in 4.21 but this
earlier removal of support from DM has been coordinated with Jens (as
evidenced by the commit being attributed to him). Making
request-based DM exclussively blk-mq only cleans up that portion of DM
core quite nicely.
- Convert the thinp and zoned targets over to using refcount_t where
applicable.
- A couple fixes to the DM zoned target for refcounting and other races
buried in the implementation of metadata block creation and use.
- Small cleanups to remove redundant unlikely() around a couple
WARN_ON_ONCE().
- Simplify how dm-ioctl copies from userspace, eliminating some
potential for a malicious user trying to change the executed ioctl
after its processing has begun.
- Tweaked DM crypt target to use the DM device name when naming the
various workqueues created for a particular DM crypt device (makes the
N workqueues for a DM crypt device more easily understood and enhances
user's accounting capabilities at a glance via "ps")
- Small fixup to remove dead branch in DM writecache's memory_entry().
