This is not the correct way to submit patches for inclusion in the
stable kernel tree.  Please read:
    https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html
for how to do this properly.

Thanks for the comment. I'll add "Cc: stable@vger.kernel.org" tag to the
patch on committing it to my maintainer tree so one the patch makes its way
up to the Linus' tree you'll get notified as usual.
