This is going the wrong way.  Nothing outside of core block layer code
should ever directly use the bdev inode.  We've been rather sloppy
and added a lot of direct reference to it, but they really need to
go away and be replaced with well defined high level operation on
struct block_device.  Once that is done we can remove the bd_inode
pointer, but replacing it with something that pokes even more deeply
into bdev internals is a bad idea.
