Aren't they all......
I am doing some heavy work in a write function.
But I have a poll wait loop (waiting for flash program end) where a lot
of time is wasted.
How do I tell the scheduler that I would like t surrender the CPU for
others to use?
I tried calling scheduler(), but that only crashed the kernel.
What is the correct way?
Sincerely,
Karsten

Look at the "Linux Device Driver" By A.Rubini & J.Corbett, there are a lot
of suggestions and examples.
