Yeah, so what needs to be fixed as well is for liblockdep to exclusively use 
tools/include/ (and extend those headers where required).

perf already uses that method and it works well.

liblockdep already uses tools/include/ in part, but even after I apply all your 
patches, there's still lib/lockdep/uinclude/ which appears to duplicate a number 
of headers.

I did a quick check - for example WARN_ON() et al is duplicated in 
tools/lib/lockdep/uinclude/linux/kernel.h.

Thanks,

	Ingo
