Atish is the one with admin for the list, I figured he'd be able to tell if it got bounced properly. If it got bounced correctly, but didn't arrive in patchwork then I don't know. Usually when a bunch of lists are CCed, multiple entries show up on lore, afair. In this case, a bunch of lists were CCed, but only the one via linux-doc appeared on lore. Konstantin, any ideas?
