title: Nice and Renice commands
body: <p>I am interested in knowing what are the kernel side methods that get called when you issue the nice and renice commands? I found the set_user_nice() in the kernel side. However it's arguments are not pid and nice value, which we use when we issue the command renice(a taskstruct &amp; nice value). Dose anyone know what functions gets called when you issue nice &amp; renice commands?</p>
