Multi-line #define's are 'orrible (IMO) -- of course, our tree is  
littered with them, but it's highly preferable to have a function  
over a define, particularly when it comes to reading the code n  
months later, trying to track something down.  In this particular  
case, the minimal overhead of calling a function rather than having  
it inline (via #define) is vastly outweighed by code-readability, and  
reduction in kernel size.
