To be clear in the future I hope to also have a baseline for:

  * xfs_bigblock

But that is *currently* [0] only possible on the following architectures
with the respective kernel config:

aarch64:
CONFIG_ARM64_64K_PAGES=y

ppc64le:
CONFIG_PPC_64K_PAGES=y

[0] Someone is working on 64k pages on x86 I think?
