It takes some more parsing of the fs structures, doable via the
SEARCH_TREE ioctl. I have an unpolished patch to show the logical chunks
(though without actual chunk usage), similar can be done for per-device
chunks. The patch was a debugging helper so it hasn't been submitted yet
until it's more user friendly. I'll keep the per-device request in mind.
