Since the IBNBD_* and _IBNBD_* constants have the same numerical value,
are the former constants really necessary?

Sorry, checked again, we defined _IBNBD_* constants to show the right
value for def_io_mode description.
If we remove the _IBNBD_*, then the modinfo shows:
def_io_mode:By default, export devices in blockio(IBNBD_BLOCKIO) or
fileio(IBNBD_FILEIO) mode. (default: IBNBD_BLOCKIO (blockio))
instead of:
parm: def_io_mode:By default, export devices in blockio(1)
or fileio(0) mode. (default: 1 (blockio))
So the user is required to enter def_io_mode as a number? Wouldn't it be
more friendly towards users to change that parameter from a number into
a string?
Thanks,
