ZONE_DEVICE and the future of struct page

The opening session of the 2017 Linux Storage, Filesystem, and Memory-Management Summit covered a familiar topic: how to represent (possibly massive) persistent-memory arrays to various subsystems in the kernel. This session, led by Dan Williams, focused in particular on the ZONE_DEVICE abstraction and whether the kernel should use page structures to represent persistent memory or not.
