Yes, but I think that is purely up to the application. Userspace knows about the new interface, the kernel doesn't, and the application has to decide how important the pkey_index stuff is. Given that we don't have a time machine (so the behavior of old kernels is frozen) I don't see anything we can do to make this any better. - R. _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
