I have /dev/mapper/via_hfciifae as the base raid device, and partitions

dmraid utility creates devices with this style of name, and if you are
seeing /dev/dm-0 it is because udev is creating that node because as far
as the kernel knows, the name of the device ( as exported by sysfs ) is
"dm-0". Udev probably shouldn't be creating device nodes for device
mapper devices, but if it does, you can simply ignore them.
Well, really we should fix the kernel, and make these /dev/dm-$DMNAME
(and thus /sys/block/dm-$DMNAME )
maybe mapper/$DMNAME (and thus /sys/block/mapper!$DMNAME) so we are
consistent with other drivers and udev will use /dev/mapper/$DMNAME
this should be fairly easy to change,
just add a name parameter to
dm_create(), dm_create_with_minor(), create_aux and alloc_dev() in
drivers/md/dm.c
and use that parameter instead of "dm-%s" when setting disk_name just
before add_disk in alloc_dev()
then pass param->name as the name parameter to dm_createXXXXX() in
drivers/md/dm-ioctl.c:dev_create()
if there are no objections i might even be tempted to send a patch.
