Not a call, probably a module_param() so that it can be switched on/off during boot. You can make the param writable so that it can be flipped run-time but updating existing workqueues would be non-trivial and I don't think it's gonna be worthwhile.
module_param()?? We can't compile kernel/workqueue.c as a module and hence i went with #define + a variable with functions to set/reset it...
I am not looking to update all existing workqueues to use it but workqueues which are affecting power for us... And if there are some very very performance critical ones, then we must better use queue_work_on() for them to make it more clear.
