Thanks!

Very strange. I didn't send out anything in-reply-to other than what git-send-email usually does. I believe I had:
[0] - no in reply to. [1] - in reply to [0] [2] - in reply to [0] [3] - in reply to [0] [4] - in reply to [0]
Is there some other way you'd prefer?
Looking full headers in <https://patchwork.kernel.org/patch/5425241/>, I confirm it is "in-reply-to" "1417563767-32181-1-git-send-email-dianders@chromium.org". Patchwork doesn't keep cover letters, but you can see at <http://www.spinics.net/lists/linux-mmc/msg29699.html>) that there is no in-reply-to.
I'm more than happy to adjust my workflow if you can give me some specifics. Thanks! :)
> In v5, I don't find a patch 1/4. Anyway, I have taken patch 2->4.
Ah, maybe because it wasn't sent to linux-mmc? I messed that up and will try to do better in the future. Sorry. :( You were in the To line, though. You can see at <https://patchwork.kernel.org/patch/5425241/>.
Do you want me to repost it and CC linux-mmc with Tony's Ack?
