It does feel a little wild to decide a patch needs to be backported
based on the commit title starting with "Fix", or whatever way was used
here. We always relied on patches being backported based on a) having a
Fixes: trailer and  b) the commit pointed out in that trailer
being present in that stable version. Or the others options shown
in Documentation/process/stable-kernel-rules.rst

Looking at the commit in question, c6fbb6bca10838485b820e8a26c23996f77ce580
there's no such a trailer. Did I miss something from
Documentation/process/stable-kernel-rules.rst?
