• 22e8bd51b   rbd: support for object-map and fast-diff ... Browse Code »

  Speed up reads, discards and zeroouts through RBD_OBJ_FLAG_MAY_EXIST
  and RBD_OBJ_FLAG_NOOP_FOR_NONEXISTENT based on object map.

  Invalid object maps are not trusted, but still updated. Note that we
  never iterate, resize or invalidate object maps. If object-map feature
  is enabled but object map fails to load, we just fail the requester
  (either "rbd map" or I/O, by way of post-acquire action).
