Just FYI, there seems to be a minor clock or timezone issue with however you're sending these emails: the Date header you sent reads "Date: Fri, 3 Apr 2020 16:56:57 +0000" but that time in the UTC +0000 timezone is (as I write this) still several hours in the future. This isn't a big deal but you probably want to look into fixing it. (Noticed because the wrong-date makes your patches stick to the top of the https://patchew.org/QEMU/ list even after other patches arrive after them.) thanks -- PMM
