No subject

code to crash quite easily (will report that separately after a while, just
thought it might be better to get the non-ext3 specific bugs squished first). I
have yet to test other file systems.

I can also give you the (qemu) testing environment images and scripts if you
wish. The breaking is done by randomly flipping each bit in the image with a
fixed probability (currently 0.0001), mounting it, cp -r:ing a directory, doing
a find -xdev, touching all files, mkdir tmp, creating and writing a file and
doing a rm -rf to the entire fs.

Steps to reproduce (in the qemu; adjust appropriately for loop-mounting the
file):

1. mount /dev/hdb /mnt -o 'errors=continue' -t ext2
2. cd /mnt
3. ls doc

After this I get the following in dmesg:

And after that the last 2 lines repeat ad infinitum.
