      Description

      ZGC currently only allows tmpfs and hugetlbfs as backing filesystems. However, there are use cases when other filesystems might be useful too. For example, DAX-enabled filesystems backed by NVRAM. We could loosen the filesystem type check done by ZGC and allow any filesystem to be used.
