kmem_cache_defrag returns the number of pages that were released by defrag actions. shrink_slab returns the number of objects released by the shrinkers. kmem_cache_defrag has no way of knowing how many objects where released by the kick methods. The kick method may have chosen to reallocate the object. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
