Ask Ondra, he should have all code what I used (I think he modified it later).
(It was some fio scripts, stacked dmcrypt test, some basic dt and fsx tests and
some simple seek test.)

I run it against several versions (no patch, without sort part, etc)
and tried to compare times and throughput.

It is of course possible I did some stupid mistake.

On top of it, I do not have anything better.
And I do not have any suitable hw for testing now, so I can just say my opinion.

I just hope you have more facts than you mentioned here to support your decision
to merge these changes.
