I see a problem. Where are we doing the ioctl on?
Ioctl on directories are probably going to die in Linux 2.5, so it's not
a good idea to add a new one. Special file? This is _really_ ugly.
Some random file? Might work, but needs at least one file on the
filesystem.
I think we should do it similar to the ext2 resizing patch and add a
resize= option to mount (or remount to be more precise).

Of course it doesn't work. We've performed a software upgrade.
