We take "large" backports from mainline all the time, as long as the
maintainers for the subsystem are ok with it.  to take one-off patches
is usually much harder as the change itself is almost always "wrong",
and then future changes are even harder to backport.

So I recommend working with the maintainers here please and see what
they want to do, if anything.
