While the pages are under I/O Michael Tsirkin and I have been doing some thinking about what it would take to allocate struct pages per 2MB area permanently, and allocate additional struct pages for 4kB pages on demand, when a 2MB area is broken up into 4kB pages. This should work for both DRAM and persistent memory. I am still not convinced it is worthwhile to have struct pages for persistent memory though, but I am willing to change my mind. -- All rights reversed -- 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
