Thanks, Greg and David. Looks like these 2 patches will cherry-pick cleanly if cherry-picked in the following sequence, on top of 4.9.74-rc1, which already has 6c9e73ef9aa7 ("tcp_bbr: record "full bw reached" decision in new full_bw_reached bit"):
$ git checkout linux-stable-rc/linux-4.9.y

I verified that this compiles without warnings, and boots, and BBR works.
Shall I prepare another version of these 2 patches, or do we think this recipe will be sufficient? (Sorry I am not more familiar with the backport-to-stable process.)
That works, those two patches are now queued up for the next stable release, thanks!

Great. Thank you, Greg and David!
