I would recommend reading Chapters 3 and 4 of Linux Kernel Development by Robert Love as when I was learning the scheduler and process management for the kernel,I found these chapters to be very useful.Further more for user space you are correct to my knowledge schedule is called for internal tasks that are taking too long in kernel land or to reschedule to another task,not for user space based tasks are TASK_INTERRUPTIBLE works fine there.
