    device-dax: Add support for a dax override driver · d200781e
    Dan Williams authored
    Introduce the 'new_id' concept for enabling a custom device-driver attach
    policy for dax-bus drivers. The intended use is to have a mechanism for
    hot-plugging device-dax ranges into the page allocator on-demand. With
    this in place the default policy of using device-dax for performance
    differentiated memory can be overridden by user-space policy that can
    arrange for the memory range to be managed as 'System RAM' with
    user-defined NUMA and other performance attributes.
