And for this item, I think there has been a bit too much emphasis on pleasing the taste of the drivers and not enough on the core VM. My concern about adding a new TLB flushing design to core VM was never taken seriously, for example. Nor was my request for performance numbers. And I did ask early in the year. I believe when you don't have any real numbers for justification, the only sane thing to do is go with the most minimal and simplest implementation first, and add complexity if/when it can be justified. -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
