There is a test suite for the pmem, dm, and dax changes
(https://github.com/pmem/ndctl?tab=readme-ov-file#unit-tests), but not
automated unfortunately. The NVDIMM maintainer team will run that before
pushing patches out to the fixes branch if you just want to lean on
that. For the rest I think we will need to depend on tested-by's from
s390 + virtio_fs folks, and / or sufficient soak time in linux-next.
