It's wrong to do that there. kflushd is just wakenup by the guy that
generated the dirty data. So if there are too many dirty buffers kflushd
was just running or it's a bug in kflushd.
btw, for better kflushd wakeup I reccommend this patch (if there was a
bug in such logic the below patch will fix it):
(it may not apply cleanly on 2.2.17pre6 but it's included into
2.2.17pre6aa2 and it was in 2.2.15aa2 too)
