[Xen-devel] can GNTTABOP_query_size return different values after migrate?
If I assume that migration is only supported between identical versions of Xen, will GNTTABOP_query_size ever return different values? The only thing I can think of is that maybe a migration between a 32 bit and a 64 bit hypervisor could cause a difference.>From a brief look at the code, DEFAULT_MAX_NR_GRANT_FRAMES is hardcodedat 32 with nothing obvious that would override it.
