Can you move the code to handle /sys/kernel/slab into mm/slab_common.c and then make slab use that? (Maybe a bit of a tough call but that has to be done at some point). Once you got a directly with settings per slab then its trivial to add another field. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
