| |
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.
