        call. Set the device into the rdev field.
        * libcsupport/src/unlink.c: Find the parent pathloc then the node
        pathloc from that node. Remove the call to find the parent given
        the node pathloc.

        disk device number from the stat rdev field.
        * libfs/src/dosfs/msdos.h: Add the length parameter to the eval
        call. Add the parent pathloc to the rmnod handler.
        * libfs/src/dosfs/msdos_dir.c: Add the parent pathloc to the rmnod
        handler.

        libfs/src/imfs/imfs_unlink.c, libfs/src/imfs/memfile.c: Add the
        parent node. Currently ignored in the IMFS.
        * libfs/src/imfs/imfs_stat.c: Return the device number in the rdev
        field.
