Byungchul, I mostly skimmed through the document.  I suggest that we
split this document.  The initial 1/4 of the document talks about
lockdep's current implementation which I believe should be combined
with the file: Documentation/locking/lockdep-design.txt. Tomorrow I
would try to understand the document in detail and hopefully provide
some useful comments.
