Hi Jan,
I tried your writeback dirty list patchset and noticed some ups/downs.
The main performance changes are
1) +2.5% fileio.requests_per_sec
2) -7.1% iostat.md0.wkB/s

So fileio got better latency and higher requests per second. That's good.

have a look whether I can reproduce that. BTW: Does that also correspond to
longer time-to-completion of the dd test?

It corresponds to the "File system outputs" line in the below output.
It should be the number of dirtied pages.
