But if the memory hotplug is synchronized, so are changes to the LMB tables. And if there are LMB read side access concernes outside of the hotplug event, ideally we should use the synchronization mechanism that hotplug uses instead of adding a new one. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
