OK, the list now reads:

Each of the following categories of code might need to be

a. The low-level interrupt-handing code.

b. The realtime process scheduler.

c. Any code that disables interrupts.

d. Any code that disables preemption.

e. Any code that holds a lock, mutex, semaphore, or other
resource that is needed by the code implementing your
new feature.

f. Any code that manipulates hardware that can stall the
bus, delay interrupts, or otherwise interfere with
forward progress. Note that it is also necessary to
inspect user-level code that directly manipulates such

I added point "f". Does that cover it?

Thanx, Paul
