Those apis will be used for other modules, so that bd_inode won't be

Here I'm not sure - is the helper really a win? It seems a bit obscure to
me. This initialization of another mapping for a bdev looks really special.
Yes, I don't like this helper at all, but gfs2 is used this way, and I
need this helper to remove 'bd_inode' from block_devcie later. I'm not
familiar with gfs2 at all but perhaps it worth to dig deeper and figure
out a proper way for gfs2.
Thanks,
