Ah! I see it now.
However, it doesn't look like you did:
keyctl add user fscache:objlist KB @s
before doing:
cat /proc/fs/fscache/objects >/tmp/object-list.txt
Did you manage to get the keyutils package installed?
You could also download:
http://people.redhat.com/~dhowells/keyutils/keyutils-1.2.tar.bz2
and try building that.
