I'll drop it, thank you.

Usually it's the case that I check for fixes/reverts once I compile the
series, and again right before I queue it up to a stable tree. In
between fixes and reverts tend to sneak in just like in this case.
In general, I also check the -rcs for fixes and reverts during their
review window, so while sometimes we send out mails with patches that
have a fix or revert upstream, they rarely make it into a released
stable kernel.
IMO, it'd be great if you have some check before sending for reviews.
The Fixes tag chain can be parsed relatively easily, after all.
True. I'll update my scripts to do that.
