The trigger for busy inodes is as simple as (I=initialization done only once): I> # dd if=/dev/zero of=/dev/shm/ext3 bs=1024 count=1 seek=$((100*1024)) I> # mkfs.ext3 -m 0 /dev/shm/ext3 # mount -oloop /dev/shm/ext3 /mnt/c # umount /mnt/c # dmesg|tail VFS: Busy inodes after unmount of loop0. Self-destruct in 5 seconds. Have a nice day... (The printk time varies -- this sequence really suffices.)

I don't know, now I'm going to play with that as I have the trigger ;). Will be back soon.
