David -
I noticed that this series got merged to net-next and shows as "Accepted"
in patchwork:
https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?id=0a2f6b32cc45e3918321779fe90c28f1ed27d2af
However, somehow patch 7 did not propagate through the netdev list and
does not show up in patchwork or the merged series!
It did get archived on the cc'd mptcp list
(https://lists.01.org/hyperkitty/list/mptcp@lists.01.org/message/KBY6UIFETMXCAOHNXQLYWKXNCHSGJ7AG/)
so hopefully your directly-addressed copy also arrived. The missing patch
won't cause a build error but does lead to a token getting exposed to
non-admin users.
I will re-send it with an extra note about where it originally fit in.
