Therefore I need to explicitly call pending_signal() before calling
kthread_run().

Right now you have to.  But the proper fix is to not require this and
fix kthread_run to work from a thread that has been selected by the OOM
killer.  In the most trivial version by moving your code into
kthread_run, but there probably are better ways as well.

Yes I see. Let me think about it, at this moment kthread_run() is still
not very clear in my mind.

Thanks for the hint.
