I just built 3.2.29, and running under KVM, I created a file system, mounted it
with -o nodev, and then unmounted it. It didn't crash.
I then mounted it without nodev, ran "mknod /mnt/null c 3 1" to create a
/dev/null character device, unmounted the file system, remounted it with -o
nodev, tried writing to /mnt/null, which failed as it should, and then
unmounted the file system. Still no crash.
Can you tell me if there was anything else special about how you ran your test?
Did it fail right on the mount? Was this the root file system that you were
testing trying to mount -o nodev, etc.?
