Thank you! I usually end up taking care of these myself :-) A rare occasion. Does this also address 4.4, 4.9 and 4.14 or do they still need backports of their own?
In Chrome OS we have the same solution for 4.14.
This patch will _definitely_ not apply cleanly for 4.4. Not sure what the best course of action is there, but in the "after the cut" notes in my post I talk about it a little bit.
On 4.9 things look similar-ish, but I don't know quite enough to know if it will work well there.
(all of this in the context that apparently some extra locking patches even for 4.14 and 4.19--see the thread in response to my posted patch).
