Why do we need to change IDE DMA timeout dynamically?
I've used it to test error recovery (for example).
Seems quite useable for developers but I would prefer not to expose it in production kernels for end users.
It seems that I have counter example of a customer asking if this timeout can be done configurable. :-) BTW, why the timeout is so damn long? 2*WAIT_CMD is 20 secs, and if DMA is not complete or interrupt pending, it may wait 10 more secs...
Thanks, Bart
