Yes, there are arseloads of misannotations.  And I do have followups
that *do* annotate that (which is exactly how that bug had been found
in the first place).  But I'd rather separate fixes from trivial
annotations - the former might need to be backported, the latter would
only cause extra PITA for backport.
