Sorry to keep replying to my own post, but, I think I found my answer
and I just thought I would share it with everyone. :)
Starting with kernel version 2.6.10: mmlist is no longer used as a
complete list of a memory descriptors on the system. Instead,
it is not only used by those memory descriptors that have pages swapped
out. If you grep the changelog
http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.10 for
"[PATCH] lighten mmlist_lock" you will find an explanation.
