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.
If we want to hide bd_inode we'll something like this helper even if
I don't particularly like it either.
But it might be a good idea to move out of this series and into the
follow on removing bd_inode, as it's rather pointless without that
context.
Yes, this sounds good, I'll remove this from v3.
Thanks,
