Thanks for reply.<br><br>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()->...<br>

</div>In x86, do_fork() is called from sys_fork()... check :<br>

<br>
While sys_fork() itself, since it's a syscall handler, is called from<br>
entry.S. Please refer to:<br>
