Before we're doing yet another round here, have you checked whether
the patchset from Yu Kuai ("PATCH RFC v2 00/10: block: fix disordered IO 
in the case of recurse split") does help in your case, too?

Hi Hannes,

Thanks for having taken a look. Yu Kuai's patch series is independent of
this patch series. The patch series "PATCH RFC v2 00/10: block: fix
disordered IO in the case of recurse split" affects the order in which
split bios are submitted by RAID drivers and by dm-linear. None of these
drivers are used in the devices I care about (Android devices).

This patch series increases IOPS for small writes whether or not the
patch series "PATCH RFC v2 00/10: block: fix disordered IO in the case
of recurse split" is applied.

Does this answer your question?

Bart.
