Mounting the attached filesystem image (fuzzed) on latest linus/master

Just wanted to add that on a kernel with linked list debugging I also
see an endless stream of the following warning, which could be related?

Unfortunately I don't have the debug info anymore, but I could try to
rebuild and see if it triggers again if necessary.
Thanks,
