Maybe I misunderstood your comment but note that I answered to that comment of yours with "So I can optimize away that PG_compound_lock with CONFIG_TRANSPARENT_HUGEPAGE=n if you want.". This is exactly what I did now, and you didn't answer to my reply, so I had no way to be sure that's the only thing you meant with TRANSP_HUGE, in which case we would have been in full agreement already. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
