Hello, Jeff.

So, something like the following. This should be applied on top of
the two previous libata patches. The amount of code in the hot path
is very small. Compared to the cpu actually taking an interrupt and
accessing hardware, it should be negligible, and this will give us
working and acceptably performing systems in the presence of most
types of IRQ problems.

Ping.

Give me another day or two. I'm working up an alternate patch for demonstration (still use the irq-expecting api, but differently).
