To the syzbot maintainers: I think this is a good example of a bisection
result that is wrong. It is unlikely that fixing typos in kernel
messages would affect whether or not the kernel hangs. Additionally, as
far as I know, the systems used by syzbot (Google Compute Engine virtual
machines) do trigger any code in the UFS driver.
