In fact, you're just making it WORSE. "short" and "greppable" is not the main issue here. "understandable" and "follows other conventions" is. And those "other conventions" are not "book binders in the 17th century". They are about operating system design. So when you mention "slab" as a name example, that's not the argument you think it is. That's a real honest-to-goodness operating system convention name that doesn't exactly predate Linux, but is most certainly not new. In fact, "slab" is a bad example for another reason: we don't actually really use it outside of the internal implementation of the slab cache. The name we actually *use* tends to be "kmalloc()" or similar, which most definitely has a CS history that goes back even further and is not at all confusing to anybody. So no. This email just convinces me that you have ENTIRELY the wrong approach to naming and is just making me more convinced that "folio" came from the wrong kind of thinking. Because "random short words" is absolutely the last thing you should look at. Linus
