Yes. But that doesn't mean that the "preempt_count()" macro necessarily needs to reflect that. In particular, we have separate macros for getting the irq bits from that shared word ("irq_count()" etc). Right now they happen to use the "preempt_count()" macro, but that's not really fundamental. No big deal either way, I suspect. Linus -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org. For more info on Linux MM, see: http://www.linux-mm.org/
