No it doesn't -- it will just crash if a caller does that. If it's a real problem then you either need to fix the callers or change add_timer_on() to transparently put it onto another CPU. I don't think it's a real problem though because CPU offlining does a stop machine and that should take care of most such races. -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
