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@xxxxxxxxxxxx". 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? --- Note: patchwork seems to find all my patches: pwclient list -w dianders@xxxxxxxxxxxx -p "" 5425241 New [v5,1/4] ARM: OMAP2+: Make sure pandora_wl1251_init_card() applies to SDIO only 5425291 New [v5,1/4] ARM: OMAP2+: Make sure pandora_wl1251_init_card() applies to SDIO only 5425311 New [v5,1/4] ARM: OMAP2+: Make sure pandora_wl1251_init_card() applies to SDIO only 5425231 New [v5,2/4] mmc: core: Support the optional init_card() callback for MMC and SD 5425301 New [v5,2/4] mmc: core: Support the optional init_card() callback for MMC and SD 5425271 New [v5,3/4] mmc: dw_mmc: Cleanup disable of low power mode w/ SDIO interrupts 5425281 New [v5,3/4] mmc: dw_mmc: Cleanup disable of low power mode w/ SDIO interrupts 5425251 New [v5,4/4] mmc: dw_mmc: Protect read-modify-write of INTMASK with a lock 5425261 New [v5,4/4] mmc: dw_mmc: Protect read-modify-write of INTMASK with a lock -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
