Thanks for the comments on this series. I'll address them in the next round. The user for this callback is not yet ready to be posted. I'll try and move this patch to the end of the series so that the series can be applied without this one. Thanks Sascha

I'm actually interested in this patch, as I am developing a thermal sensor driver that has hardware-assisted temperature-trip interrupts. I'm testing out your patches now, and will probably end up using them on my local tree. With help of this (and a few other changes I need to make), my driver should be ready to post soon. So, I'll try to post my driver soon as an example, if you'd like. I'd also appreciate a CC on any future revisions, if you don't mind. I'm subscribed to the list, but it's not always easy to pick out the signal from the noise. Thanks, Brian P.S. Time for a mild complaint: I think it seems to be a bit of a plague in the thermal subsystem; there are API's, and even user-space ABI's (!!) that have no in-kernel users! e.g., generate_netlink_event() http://article.gmane.org/gmane.linux.power-management.general/58685

Sure, I'll add you to Cc next round. I'm halfway through updating this series according to the comments I received, but got distracted. I hope to send an update next week. Sascha
