Well, that would surely _sound_ logical, but that's not the way it is.

Internally in the kernel, the runnable processes are marked as being in the
TASK_RUNNING state. The list of those processes are stored in the runqueue,
and are counted in the nr_running variable.

The scheduler operates with the states running, interruptible,
uninterruptible, stopped, zombie and swapping. It doesn't use the term
"ready".
