Parent article: Management of volatile CXL devices

"A common CXL use case involves interleaving pages across multiple devices; that forces those devices into a single NUMA node."

The current memory-tier component will lump multiple CXL-backed NUMA nodes with similar performance characteristics into a single tier - even if those nodes are attached to different sockets. This can create a confusing environment for tiering (you might end up demoting or promoting across a socket, which may be sub-optimal).

Thank you for the coverage!
