IOW still not convinced it is a good idea to push an out-of-tree obscure governor invented likely because someone didn't know they can tune 'ondemand'. Smells of "custom Android romz" and all that stuff to me, i.e. not the right way of doing things in the Linux land. If someone wants more power saving, after your patch they will need to make a conscious effort to switch to ondemand, and in the process of doing so they can also configure it to their liking just as easily. -- With respect, Roman
