[PATCH v9 3/3] loop: Add support for provision requests

, a REQ_OP_PROVISION request will translate to an fallocate() mode 0 call on the backing file. Caveat: For filesystems with copy-on-write semantics, REQ_OP_PROVISION will guarantee the success of only the next write to the provisioned range with a ENOSPC. Signed-off-by: Sarthak Kukreti Signed-off

[PATCH v9 1/3] block: Introduce provisioning primitives

to call fallocate() in mode 0 on block devices, which will send REQ_OP_PROVISION to the block device for the specified range. Signed-off-by: Sarthak Kukreti Signed-off-by: Mike Snitzer --- block/blk-core.c | 5 block/blk-lib.c | 51

[PATCH v9 2/3] dm: Add block provisioning support

Add block provisioning support for device-mapper targets. dm-crypt and dm-linear will, by default, passthrough REQ_OP_PROVISION requests to the underlying device, if supported. Signed-off-by: Sarthak Kukreti Signed-off-by: Mike Snitzer --- drivers/md/dm-crypt.c | 4 +++- drivers/md/dm
