Subject: [PATCH v3 0/4] Support DAX for device-mapper linear devices

Jens, please pick up the first 2 block patches and I'll get the other
2 DM patches staged for 4.8.

v3:
 - fixed "warning: context imbalance in 'dm_blk_direct_access' -
   different lock contexts for basic block" due to missing
   dm_put_live_table in dm_blk_direct_access's dm_get_live_table error
   path
 - refactored dm-table.c code to centralize checking if all devices in
   a DM table support DAX (removed need for target to set
   ->dax_supported)
 - included Yigal Korman's patch to add 'dax' sysfs attribute

Toshi Kani (3):
  block: add QUEUE_FLAG_DAX for devices to advertise their DAX support
  dm: add infrastructure for DAX support
  dm linear: add DAX support

Yigal Korman (1):
  block: expose QUEUE_FLAG_DAX in sysfs
