This oops is essentially the same bug, which is a ref-counter in
kref.
I believe it will never happen with the patched kernel.
I am going to release the patched aufs on next Monday.
Awesome, and thanks for the fix! Are you in touch with Ubuntu kernel
team?
I am asking as it makes sense to ask them to backport this fix,
as the bug manifestation is really ugly -- once it happens the only
cure is to reboot a machine.
Kir.
