I posted a second patch which should go on top of what's in 2.5.74-mm1 a couple of days ago. Just in case, here is a link to it. http://kernel.kolivas.org/2.5/ it's called patch-O2int-0307041440 It makes significant headway in smoothing the corner cases. I need testing at each point before I can post another update, and am doing much less frequent smaller updates now, with the aim of having no more than one patch for each -mm, so I can have a decent sized audience for each change. Andrew can you please apply this one on top in the next -mm if you are to continue testing this patch series.
