Are you happy with the v10 series? Thanks

Yes, I think they are fine except one thing. The include/linux/reboot.h is changed along with thermal*.c file. IMO it is preferable to have separate patch, I mean all reboot.h changes folded in a single patch before the thermal_*.c changes. It is actually orphaned and we should ask Matti Vaittinen <mazziesaccount@gmail.com> its acked-by as he is the author of the code you are changing. Otherwise, he will have to ack the patches which contain also thermal code which is not its area.

It is actually I tried to follow your suggestion of putting all reboot.h changes folded in a single patch before the thermal_*.c changes, but I don't think I can do this split and maintain a logic patch separation and bisectability. > orphaned and we should ask Matti Vaittinen <mazziesaccount@gmail.com> > its acked-by as he is the author of the code you are changing. > Otherwise, he will have to ack the patches which contain also thermal > code which is not its area. The reason I haven't added Matti on Cc on the series is that get_maintainer did not list him. Added him on Cc now. Maybe Matti could help acking patches 2/4 and 3/4?
