Well the information that would be exposed in /proc/slabinfo would only be faked up stuff from SLUB. The queues that are described in /proc/slabinfo do not exist f.e. (tunables do not make sense) and there are more details available via /sys/kernel/slab. There is a discussion on linux-mm with some of the people working on tools to make these to use the information that SLUB provides. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
