I don't see > a particular reason to be different from them. just because we never say 'page mapping level 4', we think 'page table level 4' or 'page directory level 4'. pte4 doesn't sound nice since we don't use pte3/2/1, but pgd4 could make some more sense than pml4. But I'm fine if you prefer to stick with pml4. Those are names we tend to memorize anyways, I don't actually know what pmd means exactly either (page middle directory)? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
