While we're at fixing up xfsidbg I have this little gem:
Kill the kdbm_vn, kdbm_vnode and xi2vnode xfsidbg commands.
The last one just printed a Linux inode (despite it's description)
and that is much better done by the inode command in
kdb/modules/kdbm_pg.c. The latter two both print the vnode (nothing
left here) and the inode and again that is better done using the
inode command. Interestingly those latter two did exactly the
same despite their quite different descriptions which weren't
correct for either command.
