Device capacity intended for use as system ram should be aligned to the architecture-defined memory block size or that capacity will be silently truncated and capacity stranded. As hotplug dax memory becomes more prevelant, the memory block size alignment becomes more important for platform and device vendors to pay attention to - so this truncation should not be silent. This issue is particularly relevant for CXL Dynamic Capacity devices, whose capacity may arrive in spec-aligned but block-misaligned chunks.
