Overloading ->change_queue_depth with the queue ramp up / down functionality has been a bad idea. It lead to a large amount of code duplication, and driver keep getting the the API wrong and end up accidentally enabling the queue depth tracking while getting it wrong.
This serie instead adds a flag to enable queue tracking and handles it entirely in core code. This is a preparation for various logic changes to the queue depth tracking code. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
