This series contains some cleanups and new test suggestions from Catalin from an earlier discussion. https://lore.kernel.org/linux-mm/20201123142237.GF17833@gaia/ This series is based on v5.11-rc4 and has been tested on arm64, s390 and x86 but has only been build tested on riscv, arc etc. It would be great if folks could test this on these platforms as well.
