1) please change 'is' and 'task' around so that it reads nicer:

   if (task_is_stopped(t))

instead of the tongue-twister:

   if (is_task_stopped(t))

2) please change task_is_loadavg() to something more sensible - i didnt 
know what it meant when i first saw it in -mm's sched.c. 
task_is_uninterruptible() would be the logical choice ...
