I CCed a bunch of lists and people to make sure everyone is aware of
that patch, as it otherwise might fall through the cracks.
Markus, quick question: do you have (a) an interest in contributing a
change to Linux or (b) did you just post this because Mario asked you to
do so in https://bugzilla.kernel.org/show_bug.cgi?id=217063#c25 ?
If it's (a) then you might want to take a closer look at
https://www.kernel.org/doc/html/latest/process/submitting-patches.html
, as your patch lacks a few important things before it can be applied
(most notably a Signed-off-by tag)
If it's (b) I wonder if it would be easier for everyone involved if some
kernel developer could create a patch own their own, as that likely is
way easier to review and thus likely gets the problem resolved a lot faster.
Ciao, Thorsten
