Nothing much, we won't be properly accounting the numa access in the host. What we want to achieve is to convert a guest access of the page to a host fault so that we can do proper numa access accounting in the host. This would enable us to migrate the page to the correct numa node. > > I'm trying to figure out whether I need to mark this with a stable tag > for 3.14. > > -aneesh _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
