Peter, this is purely a matter of good software engineering practices.  I 
hadn't realized you were so passionate about avoiding initialization of 
global atomic_t variables, even though it usually suffices.

I assume you wouldn't object to removing all such cases in the kernel.

	$ grep -r "atomic_t.*= ATOMIC_INIT(0)" * | wc -l
	104

Unless David Miller has any input, I'll happily defer to your 
maintainership of lockdep in this matter.  Thanks for looking at the 
patch.
