Ilya Dryomov	22e8bd51bb	rbd: support for object-map and fast-diff 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).

rbd: support for object-map and fast-diff

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).

libceph, ceph: move ceph_calc_file_object_mapping() to striper.c

ceph_calc_file_object_mapping() has nothing to do with osdmaps.
