Not all pm operations involve freezer. The exclusion is against mem hotplug at this point, right? I don't think it's a good idea to add such hack to fix a mostly theoretical problem and it's actually quite likely someone would be scratching head trying to figure out why the hell the CPU was hot spinning while the system is trying to enter one of powersaving mode (we had similar behavior in freezer code a while back and it was ugly). So, let's either fix it properly or leave it alone. Thank you. -- tejun -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
