Greeting All

I just wanna clarify basic concept about the two io probes (start) & 
(wait-start).

Does (wait-start) do the required data transfer specified in args[0]->b_count 
right before the associated (wait-done) fires !!

OR does the two associated probes (wait-start & wait-done) indicate a waiting 
time period ONLY (without actual data transfer) in a busy I/O system.

Response appreciated ...
