[Enes Albay - انس الباى]

 Hi!

anybody knows that where is set_user_nice() function called in the kernel?
i couldn't find that.  i just found that in forking operation
do_fork()->copy_process()->
dup_task_struct() called then set_user_nice()
called but i couldn't find that where. Also how/where do_fork() function
called in kernel i couldn't find.

Thanks in advance...
