We also have not made the rule that a shutdown will complete in a
specific amount of time either, so there is no problem if that takes a
long time as well.

OK, I will submit a new patch which just holds device lock.

Alan, do you have objections on the new one?

No objections. �It should end up being pretty much like one of the
patches you posted earlier.

Holding parent reference count is missed in earlier version.

Should there be an option for a debug log of each device name just
before its shutdown routine is called?

We have had the below before calling shutdown callback.

          dev_dbg(dev, "shutdown\n");

Thanks,
