This has nothing to do with the common definition of "safety".Terms change their meaning based upon their use and context. The author has a clear use in mind - memory safety. The rules of arugment existed long before the linux kernel. You don't get to change terms introduced within a arugment with a clear meaning because it helps you create a strawman. If you want to change the definition of a term mid arugment, you telegraph it. Once again, this is called conflation.
