Well, the acpi way works with more than one piece of code "listening" for powerdowns... and does not seem that ugly to me. Okay, so accessing system_state is not _that_ nice... aha, and perhaps I understand why 1/2 of this series is right... it called prepare for S4 even when we had shutdown in /sys/power/disk, right? Hmm. Okay, I think I can ACK both of these patches, but ACPI people should have chance to comment, and it probably needs to stay in -mm for a while. -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
