rd.o module refcount problem

[Maneesh Soni (maneesh@in.ibm.com)]

The module ref count for rd.o module is not adjusted and remains 1 while doing 
the following things. 

[root@llm01 mod]# insmod /sdb/linux-2.5.70/drivers/block/rd.o
[root@llm01 mod]# lsmod
Module                  Size  Used by
rd                      5568  0 - Live 0xf88b5000
[root@llm01 mod]# mkfs -t ext2 /dev/ram0
.
.
[root@llm01 mod]# lsmod
Module                  Size  Used by
rd                      5568  1 - Live 0xf88b5000

mount/umount of /dev/ram0 does not change the rd.o module ref count. 

So, who is supposed to release the rd.o module gracefully? 
Also mount /dev/ram0 should hold a ref and umount should release the same.

Same test on 2.4.20 looks correct and mount increments the ref count and
umount decrements the ref count.
