Hi Jens,

they series contains various improvement for block I/O accounting.  The
first bunch of patches switch the bio based drivers to better accounting
helpers compared to the current mess.  The end contains a fix and various
performanc improvements.  Most of this comes from a series Konstantin
sent a few weeks ago, rebased on changes that landed in your tree since
and my change to always use the percpu version of the disk stats.

Thanks for picking this up.

One note about possible further improvement in reply to first patch.
