Subject: [PATCH v5 0/5] Introduce block provisioning primitives

Next revision of adding support for block provisioning requests.

Changes from v4:
- Add fix for block devices invalidating pagecache if blkdev_fallocate()
  is called with an invalid mode.
- s/max_provision_sectors/provision_max_bytes in sysfs.

Sarthak Kukreti (5):
  block: Don't invalidate pagecache for invalid falloc modes
  block: Introduce provisioning primitives
  dm: Add block provisioning support
  dm-thin: Add REQ_OP_PROVISION support
  loop: Add support for provision requests
