Check out a recent tree (either Linus' current tree or ideally
the net-2.6.26.git tree from

git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6.26.git

and look at net/sched/cls_flow.c and the recent changes to
net/sched/sch_sfq.c for external classifiers. There are also
a number of other incompatible changes that your patch needs
to be adapter to, most importantly the use of the new netlink
infrastructure.
