Ah I see - I don't think that has effectively changed. 'rdev' still
contains a statically allocated badblocks structure (as opposed to
gendisk, which just stores a pointer). md used to dynamically allocate
the storage space inside badblocks (bb->page), and that is still the
case using badblocks_init.
