Yeah it wasn't probably clear enough, but this is stable-only patch, as
upstream avoided the (then-unknown) problem in 4.19 as part of a far
more intrusive series. As I've said in my previous reply to this thread,
I don't think we can backport that series to stable (e.g. it introduces
a set of new kmalloc caches that will suddenly appear in /proc/slabinfo)
so I think this is a case for exception from the stable rules.
