This is not the first time we discuss this topic. Please, read the archive. We are going to complete the ongoing work first and, after that, I personally will consider applying this kind of tree-wide change, or any other that may serve to the same purpose, to my tree. At this moment this change will only create confusion and potentially bring a halt to the main idea behind all this, which is to enable -Wimplicit-fallthrough. There are only ~100 of these warnings left in linux-next. Having said that, please, cultivate the practice of showing every code you touch to a compiler first before proposing any patches. Otherwise, your opinions and ideas won't be that popular. Also, if your intention was to do a tree-wide change to replace all the existing fall-through comments, you failed to take into account all the info contained in the article you mention, which by the way is incomplete.
