Probably. It doesn't have any Fixes tag (this is a fix, but the bug
is caused not by a particular commit, rather by a combination of
changes and code flows from the past), but it still can be
backported, right.

Thomas, should I queue a v2 with this tag added?

Cc: stable@xxxxxxxxxxxxxxx # 5.14+

Or it can be picked up automatically?
