cryptoloop on 2.4.22/ppc doesn't work

[Christian Jaeger <christian.jaeger@ethlife.ethz.ch>]

Hello

I cannot seem to get crypto loopback to run.

This is 2.4.22 + patch-cryptoloop-jari-2.4.22.0 + 2.4.22-ben1 (but the
latter does not touch any of the crypto or loop devices), all from
kernel.org.

Linux lombi 2.4.22-ben1 #4 Son Aug 31 22:58:54 MEST 2003 ppc unknown

root@lombi root# LANG=C losetup -e blowfish /dev/loop1 christest

root@lombi root# stat christest | grep Blocks
  Size: 20971520  	Blocks: 41008      IO Block: 4096   Regular File

while the modules listed below are loaded.

This is Debian woody, /sbin/losetup from mount package 2.11m-1

Why doesn't it work?

Thanks,
Christian.
