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.
