I wasn't aware that you were considering the inclusion of Linus' entire 
email in the document.  There exists a point where CodingStyle becomes so

expecting only an addition that would explicit document the acceptable and
unacceptable uses of 'volatile' in kernel code with perhaps a link to his 
email.
