Fixing a bug in the Linux kernel is not "much easier". You are taking a purely engineering viewpoint, but life is not like that. There are lots of copies of Linux kernels around and in use. The issue is not fixing the kernel per se, it is propagating that change to all Linux kernels in use -- THAT'S another matter entirely, and is far far more difficult than making sure that a kernel fix is qualified and widely proopagated.
