The control device for a nvdimm_bus is registered as an "nd" class device. The expectation is that there will usually only be one "nd" bus registered under /sys/class/nd. However, we allow for the possibility of multiple buses and they will listed in discovery order as ndctl0...ndctlN. This character device hosts the ioctl for passing control messages. The initial command set has a 1:1 correlation with the commands listed in the by the "NFIT DSM Example" document [1], but this scheme is extensible to future command sets. Note, nd_ioctl() and the backing ->ndctl() implementation are defined in a subsequent patch. This is simply the initial registrations and sysfs attributes.
