This patch makes the cache_cleaner workqueue deferrable, to prevent unnecessary system wake-ups, which is very important for embedded battery-powered devices. do_cache_clean() is called every 30 seconds at the moment, and often makes the system wake up from its power-save sleep state. With this change, when the workqueue uses a deferrable timer, the do_cache_clean() invocation will be delayed and combined with the closest "real" wake-up. This improves the power consumption situation. Note, I tried to create a DECLARE_DELAYED_WORK_DEFERRABLE() helper macro, similar to DECLARE_DELAYED_WORK(), but failed because of the way the timer wheel core stores the deferrable flag (it is the LSBit in the time->base pointer). My attempt to define a static variable with this bit set ended up with the "initializer element is not constant" error. Thus, I have to use run-time initialization, so I created a new cache_initialize() function which is called once when sunrpc is being initialized.
