This looks correct. I find it odd that we used to check the old sp to figure out whether to put SA_ONSTACK into the signal frame, but I do think the new behavior is better. In any event, this changes the compat case to work like the native case, and no one noticed when the native behavior changed, so it's fine by me. --Andy -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
