Yeah, this got applied for some reason without the prerequisite
patches. It is from a two patch series, the other being here:

https://lore.kernel.org/linux-kselftest/20200813205722.1384108-1-urielguaja=
rdojr@gmail.com/

which in turn depends on another patchset which didn't make it into 5.9.

Again, I don't know why this was applied without it's prereqs. Sorry about =
that.
