print contents of runqueue

Hi, I want to print contents of runqueue of my current processor. I got the pointer to current task_struct. To get runqueue, I called task_rq(). When compiled the module, it gave an error. Actually struct runqueue and task_rq() is not in any header file. It is present in kernel/sched.c Is there any way to access this structure without making changes to kernel . -- Regards, Kashish
