Rather scary
I understand that Linus is far above us mortals, but this volume of code seems a little scary to me. Look at the AMD driver files for example, like atombios.h. 8000+ lines of magic numbers. After reviewing the first few hundred lines your eyes go squiggly and it would be easy to mistake a 0x08 for a 0x00. I'm not sure even the many eyeballs/shallow bugs theory would hold here.
If was a government employee of a certain three letter agency, I would be eyeing this level of change with much interest. We already know that people have tried to slip in one-character exploits to people's source code servers...
