kthread Working

[Gaurav Mahajan]

Hi,

I have a douby regarding  kthread working.

How can we check that a kthread is working or exited.
It  may exit beacuse of call to do_exit in threadfn or callling kthread_stop
function on task_struct (correct me if i am weong).

I want to check that if kthread has finished its work or not.
If not then what should I call so that kthread gets killed.
If it is finshhed then which function I should call so that as to free
kthread resources.

Regards,
Gaurav Mahajan.
