Subject: [PATCH v3 0/2] iostat update for dax and libnvdimm

This patch-set adds/updates iostat functions to DAX and
libnvdimm.

Patch 1 adds iostat support to the DAX read/write path since
it only measures metadata at this point.

Patch 2 updates nd_iostat_start() and nd_iostat_end() to use
the generic iostat interfaces.

v3:
 - Use generic_start_io_acct() and generic_end_io_acct() for
   both dax and libnvdimm. (Dave Chinner, Dan Williams)

v2:
 - Set a minimum of one sector. (Dan Williams)

Toshi Kani (2):
 1/2 DAX: enable iostat for read/write
 2/2 libnvdimm: use generic iostat interfaces
