The driver submits mutliple async requests. The number sent is either
the device's max or 8, which ever is smaller. When the driver sees a
completion, it writes a message to the kernel log then submits another
request. If anyone has a better idea how to report async events, I'm
all for it.

To test, I just set the temperature threshold to below the current
temparature to trigger the smart async event.
