These changes are in linux-mm tree (https://www.ozlabs.org/~akpm/mmotm/
with a mirror at https://github.com/hnaz/linux-mm)

I beleive they will be coming in 5.11.

Just pulled from that tree and gave it a try, it actually fails to build:

Hmm, it was buidling fine with v5.10-rc2-mmotm-2020-11-07-21-40.
I'll try to see what could cause this.

Do you build with defconfig or do you use a custom config?
