    device-dax: Add /sys/class/dax backwards compatibility · 730926c3
    Dan Williams authored
    On the expectation that some environments may not upgrade libdaxctl
    (userspace component that depends on the /sys/class/dax hierarchy),
    provide a default / legacy dax_pmem_compat driver. The dax_pmem_compat
    driver implements the original /sys/class/dax sysfs layout rather than
    /sys/bus/dax. When userspace is upgraded it can blacklist this module
    and switch to the dax_pmem driver going forward.
    
    CONFIG_DEV_DAX_PMEM_COMPAT and supporting code will be deleted according
    to the dax_pmem entry in Documentation/ABI/obsolete/.
