Hi,
I'm not sure that this one makes a real sense for backport.
It can't hurt, but it does not fix a real issue, it just voids a
potential spurious message.
In my original mail, there is no "stable@" or "fix" or "bug" keywords or
"Fixes:" tag.
There is also apparently no patch in this backport serie that relies on
this patch.
Why has it been selected?
(same for 5.15 and 5.19)
