Thanks for reply.

I also asked that set_user_nice where and when is called(file and line).  I
think it is not called after each forking operation, isn't it? Could you
give calling order between functions from do_fork() like that
func1()->func2()->...

Regards.

Hi!

anybody knows that where is set_user_nice() function called in the

kernel?

quoted

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.

In x86, do_fork() is called from sys_fork()... check :
http://lxr.linux.no/#linux+v3.1.1/arch/x86/kernel/process.c#L235

While sys_fork() itself, since it's a syscall handler, is called from
entry.S. Please refer to:
http://lxr.linux.no/#linux+v3.1.1/arch/x86/ia32/ia32entry.S#L475
