Ok I've got the sysfs relevant patches ported to 2.6.25, and am looking
at how to extend it to handle /sys/kernel/uids.  You have tagging tied
intimately to struct class.  So the question is should I generalize the
taggint to deal with kobjects instead, or create a struct class user
and make /sys/kernel/uids a symlink to /sys/class/user/uids?

Opinions?

thanks,

PS: If you want me to post the patchset before handling userns I can do
that, otherwise I was just going to wait until I'm done with userns.
