How the hell is that supposed to work with cold dcache? You don't have ->get_parent() there at all...
There *IS* a reference to parent directory in those suckers - not the same kind as in normal unix filesystems (".." is not a directory entry there - it's all fake), but it's doable. be32_to_cpu(AFFS_TAIL(sb, bh)->parent) would be the inumber you need, where bh is the inode block of directory.
So it can be done, but not in this form. NAK for the time being...
