-         This option determines if the kernel forces gcc to inline the functions
-         developers have marked 'inline'. Doing so takes away freedom from gcc to
-         do what it thinks is best, which is desirable for the gcc 3.x series of
-         compilers. The gcc 4.x series have a rewritten inlining algorithm and
-         disabling this option will generate a smaller kernel there. Hopefully
-         this algorithm is so good that allowing gcc4 to make the decision can
-         become the default in the future, until then this option is there to
-         test gcc for this.
