Yes, the original patch comes from chromium gerrit:
https://chromium-review.googlesource.com/c/chromiumos/third_party/kernel/+/3482475/4
and after reworking but before sending to the mailing list, I've asked
all involved guys for ack and it was done internally on gerrit:
https://chromium-review.googlesource.com/c/chromiumos/third_party/kernel/+/3666997

Actually it may not be an issue for the next version since the
suggested by Sean approach is quite different so I would most likely
end up with reduced SoB/Co-dev-by in the next version.
