It can't go away between reserve and unreserve, and I think it also can't be evicted then. Havn't checked how ttm implements that. cheers, Gerd _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
