It looks like the original (before your patch) 1k failures due to a bug introduced via the block.git tree, which has since been fixed in Linus's mainline tree as of today. It wouldn't surprise me if the bug interacted poorly your changes, so things will probably better with your patches applied directly on top of the tip of Linus's tree. That being said, it looks like there were still regressions introduced on the 4k configuration, so I'm in the middle of rerunning my baseline and trying out your patches as well.
