[PATCH v6 0/5] Introduce block provisioning primitives

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

This patch series covers iteration 6 of adding support for block
provisioning requests.

Changes from v5:
- Remove explicit supports_provision from dm devices.
- Move provision sectors io hint to pool_io_hint. Other devices
  will derive the provisioning limits from the stack.
- Remove artifact from v4 to omit cell_defer_no_holder for
  REQ_OP_PROVISION.
- Fix blkdev_fallocate() called with invalid fallocate
  modes to propagate errors correctly.

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
