That's what I derived from the numbers you posted for null_blk. If Ming has
posted performance results for other drivers than lpfc, please let me know
where I can find these. I have not yet seen these numbers.

Yes, this is tiresome. It is very annoying to me that others keep introducing
so many regressions in such important parts of the kernel. It is also annoying
to me that I get blamed if I report a regression instead of seeing that the
regression gets fixed.
