I was about to send Tiezhu Yang's fix to Linus.   I'll rebase mm-hotfixes-stable
to drop that patch, so you own it now!

Please note that your version lacks an explicit cc:stable, but I suppose the
stablebots will scoop it up anyway.

"Original-fix-from" isn't a thing.  In fact it seems to be the first
time this has been used.  Grepping for  "Original-.*:" shows
all sorts of innovations, including "Based-on-the-original-screenplay-by:".

I guess Documentation/process/submitting-patches.rst and checkpatch
lost this fight a long time ago.
