Hm. the assumption is that `avg_objsize' cannot be larger than `max_objsize', which is `int object_size;' in `struct kmem_cache' from slab_def.h and `unsigned int object_size;' in `struct kmem_cache' from slab.h. avg_objsize = total_used / total_objects; -ss -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
