This patch-set adds DAX support to device-mapper dm-linear devices used by LVM. It works with LVM commands as follows: - Creation of a logical volume with all DAX capable devices (such as pmem) sets the logical volume DAX capable as well. - Once a logical volume is set to DAX capable, the volume may not be extended with non-DAX capable devices. The direct_access interface is added to dm and dm-linear to map a request to a target device. The patches replace v1 series at: http://git.kernel.org/cgit/linux/kernel/git/snitzer/linux.git/log/?h=wip v2: - Fix issue with partitioning. - Change to add DAX flag to a request queue. --- Toshi Kani (3): 1/3 block: add QUEUE_FLAG_DAX for devices to advertise their DAX support 2/3 dm: add infrastructure for DAX support 3/3 dm linear: add DAX support --- drivers/block/brd.c | 4 +++- drivers/md/dm-linear.c | 23 ++++++++++++++++++++++- drivers/md/dm-table.c | 23 ++++++++++++++++++++--- drivers/md/dm.c | 36 +++++++++++++++++++++++++++++++++++- drivers/md/dm.h | 1 + drivers/nvdimm/pmem.c | 1 + drivers/s390/block/dcssblk.c | 1 + fs/block_dev.c | 5 +++-- include/linux/blkdev.h | 2 ++ include/linux/device-mapper.h | 16 ++++++++++++++++ 10 files changed, 104 insertions(+), 8 deletions(-)
