I see the benefit, but this is moving in the wrong direction.
struct bdev_inode is private to hide the struct inode. Which at
the momen is a bit pointless given the bd_inode pointer in struct
block_device.
So we have two choices here that make sense:
1) remove struct bdev_inode and kill the illusion that the inode
is a private implementation detail
2) remove direct references to bd_inode entirely. Most of them are
to i_size which already has proper helpers that should be used,
and the rest can probably be covered with a handful wrappes or
is bogus anyway
