Not sure I follow? I believe I've kept all the badblocks functionality
RAID already had..


On a related note, something I observed when testing with md:

md's badblock list is per-device, and can be seen at:
	/sys/block/md0/md/dev-pmem0/bad_blocks

Now if we have badblocks in the gendisks too, there is also:
	/sys/block/pmem0/bad_blocks

The two are separate 'accounts' maintained by separate drivers (md for
the former, and pmem for the latter). This can potentially be
confusing..

Should we consolidate the two, i.e. make md (re)use the gendisk
badblocks for its purposes too?
