If you are, then I&#x27;mma slap a big [citation needed] on that comment. While searching for that citation, do keep in mind that writing code for OS kernel is usually going to require <i>much</i> more in-depth knowledge of <i>how</i> a compiler optimizes things and the like than writing code for some CRUD application. This means that -not infrequently- single-character errors <i>do</i> have substantial significance.
