[PATCH v3 0/4] Support DAX for device-mapper linear devices
From: Mike Snitzer
Date: Thu Jun 23 2016 - 17:06:49 EST
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
