That's better than splattering the logic into callsites. The patch makes no change to code size but that's because gcc is silly. Mark mem_cgroup_zoneinfo_zone() as noinline and the patch shrinks .text by 40 bytes. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
