From: Li Li <dualli@xxxxxxxxxx> To improve the user experience when switching between recently used applications, the background applications which are not currently needed are cached in the memory. Normally, a well designed application will not consume valuable CPU resources in the background. However, it's possible some applications are not able or willing to behave as expected, wasting energy even after being cached. It is a good idea to freeze those applications when they're only being kept alive for the sake of faster startup and energy saving. These kernel patches will provide the necessary infrastructure for user space framework to freeze and thaw a cached process, check the current freezing status and correctly deal with outstanding binder transactions to frozen processes.
