I have already implemented tracing for SLAB, SLUB and SLOB, and patched relayfs to work early on (just after kmem_cache_init() runs). Currently, I'm working on the userspace tool, so much of the coding is largely finished. I wanted to submit the relay stuff, but couldn't contact its maintainer. If anyone wants to take a look, I could set up a git repo somewhere (which has to be done anyway, at some point).
