Note that if you submit a new series in-reply to a semirandom existing
one, CI/Patchwork will not pick it up correctly. in-reply-to is just for
resending individual patches in a series, as a reply to the corresponding
patch in the original one. If you add/remove/change the numbers of
patches, it needs to be a new one.
