Um, NTFS uses address spaces for things where ->host is not an inode at all
so doing host->i_sb will give you god knows what but certainly not a super
block!

As long as your patches don't break that is possible to have I am happy...
But from what you are saying above I have a bad feeling you are somehow
assuming that a mapping's host is an inode...
