    device-dax: make align a per-device property · 33cf94d7
    Joao Martins authored
    Introduce @align to struct dev_dax.
    
    When creating a new device, we still initialize to the default dax_region
    @align.  Child devices belonging to a region may wish to keep a different
    alignment property instead of a global region-defined one.
