Subject: [PATCH v5 0/2] dax, dm: stop requiring dax for device-mapper
Changes since v4:
* redo a botched send of v3
* rebase on 4.14-rc1
* rewrite the changelog of patch2 to drop broken references to the
"built-in portion of device-mapper" (Mike)
---
Bart points out that the DAX core is unconditionally enabled if
device-mapper is enabled. Add some config machinery and stub routines to
allow device-mapper to build and run with CONFIG_DAX=n.

Dan Williams (2):
dax: introduce CONFIG_DAX_DRIVER
dm: allow device-mapper to operate without dax support
