Feature: slabinfo

[hodgesds]

Has there been any consideration for including slab info? It should be easily available from /proc/slabinfo (with the proper kernel configuration). I made a small POC exporter of the info and it's rather useful for getting insight into kernel object use. Here's a quick example graph I made while kicking off a large grep on my NAS. The cardinality can be rather high, so it probably needs a regex of allowed objects.

Seems reasonable, even if not enabled by default.
