That was my gut feel too. However, it seems from Carsten and Jörn discussion of read/write XIP on Flash (and some new Phase Change) memories that having the struct pages has a lot of potential benefits. Wouldn't it also allow most of the mm routines to remain unchanged. I just worry that it would be difficult to set apart these non volitatile pages that can't be written too directly.

But that's handled by ioremap()ing it right? - 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/
