linux.git/include/linux/ceph/striper.h, branch v6.12.80 Clone of https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git rbd: support for object-map and fast-diff 2019-07-08T12:01:45+00:00 Ilya Dryomov idryomov@gmail.com 2019-06-05T17:25:11+00:00 22e8bd51bb0469d1a524130a057f894ff632376a 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). Signed-off-by: Ilya Dryomov <idryomov@gmail.com> 
Speed up reads, discards and zeroouts through RBD_OBJ_FLAG_MAY_EXIST

Invalid object maps are not trusted, but still updated.  Note that we
