I understand that you do not want a whole set of such "fix one such bug at a
time" patches, but the bottom line is that these lockdep warnings for known
problems interfere with "normal" debugging because further lockdep checking is
disabled. I do not feel qualified to detect other cases and fix them. Only when
a warning hits my logs am I qualified to fix and test.
