Unfortunately this is bullshit. 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.
