This is fine

This is less helpful. Each of the printks explains why the bug
triggers. In theory you can work this out from the BUG_ON line number,
but *only* if your source files match those of the reporter, which isn't
the case in an annoyingly large number of bug reports ... speaking as
someone who seems to get to diagnose large numbers of bugs, it makes my
life harder.
