    libnvdimm, pmem, pfn: make pmem_rw_bytes generic and refactor pfn setup · 200c79da
    Dan Williams authored
    In preparation for providing an alternative (to block device) access
    mechanism to persistent memory, convert pmem_rw_bytes() to
    nsio_rw_bytes().  This allows ->rw_bytes() functionality without
    requiring a 'struct pmem_device' to be instantiated.
    In other words, when ->rw_bytes() is in use i/o is driven through
    'struct nd_namespace_io', otherwise it is driven through 'struct
    pmem_device' and the block layer.  This consolidates the disjoint calls
    to devm_exit_badblocks() and devm_memunmap() into a common
    devm_nsio_disable() and cleans up the init path to use a unified
    pmem_attach_disk() implementation.
