[PATCH v2 0/2] Add DAX ABI for memmap_on_memory

[Vishal Verma]

The DAX drivers were missing sysfs ABI documentation entirely.  Add this
missing documentation for the sysfs ABI for DAX regions and Dax devices
in patch 1. Add a new ABI for toggling memmap_on_memory semantics in
patch 2.

The missing ABI was spotted in [1], this series is a split of the new
ABI additions behind the initial documentation creation.
