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 from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
