Subject: Detecting runnable process?

I'm writing some kernel code that given a task's task_struct must
decide if it is runnable, and hasn't crashed or exited. So far here's
what I've come up with:

struct task_struct *my_task;
... snip ...
if(likely(my_task != NULL && pid_alive(my_task) == true)) { return my_task; }

Is this correct?
