It also only affects those fairly rare lockdep users as well, and the only
affect is to throw a nasty warning message.  Isn't lockdep all about throwing
nasty warning messages?

Linus I think this can be the start of a new development tradition.
The annual birthday scolding from Linus.  I am certain we will all
appreciate the attention.

Unfortunately I have been extremely busy this last week and haven't
been able to do anything so you have only seen my backup plan in
effect where reasonable kernel developers notice the instances I
missed and on a case by case basis trivially fix it.  I believe Greg
has been queuing up many of those case by case fixes.  A few have been
flowing through other maintainers.

Wolfram Sang was figuring out if he could get coccinelle (whatever
that is) to find more of them.

It is my intention to go through all of the reports make certain everything
is getting fixed, and also to look through and see if I can find any more
cases that I have overlooked.
