commit 26f55a59dc65ff77cd1c4b37991e26497fc68049 upstream.

I am not finding this in Linus's tree and even not seeing this change in
master branch also. Am I missing something?

Both are in -net tree at this point, thus commit sha won't change anymore. David or
Jakub will likely send their -net PR to Linus today or tomorrow for landing in
mainline. For stable things had to move a bit quicker given the announcement in [0]
yesterday. Timing was a bit unfortunate here as I would have preferred for things to
land in stable the regular way first (aka merge to mainline, cherry-picking to stable,
minor stable release, then announcement).

Thanks,
Daniel
