These patches actually depend upon that bug fix not being applied. Look at the patches, they reference and use the reset workqueue the bug fix removed. Anyways, I sorted through all of these merge hassles, and fixed up the off-by-one bug Ben spotted in patch #2 because I was tired of waiting and didn't want these patches to just keep rotting in patchwork.
