I can see what each patch does, but what's the overall result? We talked about this a couple years back at the Embedded Linux Conference. In response to my whining about how ugly XIP hacks were preventing me from merging my AXFS filesystem, you said, "We have an XIP framework. Why don't you fix that?" This is fixing the the XIP framework. The old XIP framework just didn't work for embedded, mostly because it was page based. Nick decided to help and proposed a way to rework the XIP framework to be pfn based instead of page based. It turns out the s390 guys (creators and only users of the XIP framework) prefer the pfn based scheme. Now the creators and only users of the XIP framework are excited about the very changes which allow the framework to be used by us deviant embedded types. Everyone is happy! -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org. For more info on Linux MM, see: http://www.linux-mm.org/ .
