I didn't check closely but there seems to be some filesystem specific stats under /proc at least. No idea how useful those are as attack vectors. I also suspect there are per-module knobs under /proc and /sys that can be used to get indirect information. Many subsystems have implemented their own slab wrappers in the past and they keep popping up every now and then.
