IMFS stat st_dev and st_rdev wrong

[Chris Johns]

The IMFS code does:

case IMFS_DEVICE:

io = &the_jnode->info.device;
buf->st_dev = rtems_filesystem_make_dev_t( io->major, io->minor );
break;

to fill in the node, how-ever the SUS states[1]:

dev_t st_dev Device ID of device containing file.
dev_t st_rdev Device ID (if file is character or block special).

This can be seen with the BSD ls command where the nodes are not display correctly. Changing the IMFS to support rdev will break code which is wrong and should be fixed. The MSDOS file system has this code:

vol->dev = stat_buf.st_dev;

I have changed the IMFS to also fill in the st_redev field, but what is the device number for the IMFS itself ?
