Project To Mainline Android Kernel Changes Formed

As has been repeatedly reported, Linus is fine with someone taking a version of the Linux kernel and forking it off in their own special direction, as the Android developers have done. If you want to put some of the those features back into his main line, though, they will have to meet his standards, and those of the people he has trusted to manage the kernel changes. If the Android developers' changes were acceptable, they would already have been merged.

"wakelocks", for example, are a kludge to cover up some very lax user-space coding standards, and are not acceptable.

There is a lot of recent work (not really finished, IMO) to handle micromanaging power consumption for System on Chip (SoC), battery-powered devices, both in the kernel itself and through controlling userspace. If Android developers want to be using the mainstream kernel, they should be preparing to use the new interfaces and tools, while helping to find any real issues, rather than whining "why won't you just do it our way?".

My contribution to the Linux kernel is incredibly minor, but it had to go through exactly the same vetting process, and the result was a better change.
