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. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
