Greetings Vincenzo.
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.
Hope this Helps,
Nick
