In order to add layering support we're going to want to separate the mapping information from the image information more clearly. This was begun recently but these two patches do the bulk of the movement of the rest of the mapping-related fields. -Alex [PATCH 1/2] rbd: move dev_id and list links into mapping [PATCH 2/2] rbd: move more stuff into mapping
