Thanks for the idea. Unfortunately, in this case I think I need to wait
for the thread to stop. The thread is processing data. The data is going
to be removed and can't be removed until the processing has been halted
and the removal noted. The waiting thread has received the notice that
the data is going away and should clean up.
I'm going to use a condition variable to signal the end of the thread.
Now I need to work out how to do that. Any recommendations for a kernel
condition variable?
Thanks for the ideas,
