How should this be routed? There's a pending change on the same
region of code and if this patch is routed outside percpu tree it'd
cause a conflict and I can't route this as lockless_dereference()
isn't in the mainline yet. Maybe expose a git branch which contaisn
lockless_dereference() so that percpu can pull it in?

Thanks.
