One thing I'd like to avoid is an MPX vma getting merged with a non-MPX vma. I don't see any code to prevent two VMAs with different vm_ops->names from getting merged. That seems like a bit of a design oversight for ->name. Right? Thinking out loud a bit... There are also some more complicated but more performant cleanup mechanisms that I'd like to go after in the future. Given a page, we might want to figure out if it is an MPX page or not. I wonder if we'll ever collide with some other user of vm_ops->name. It looks fairly narrowly used at the moment, but would this keep us from putting these pages on, say, a tmpfs mount? Doesn't look that way at the moment. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
