Hal pointed me to your patches for this, since I'm working on adding InformInfo / Notice support. I believe that a good portion of the code there is usable. What I didn't see in the patch was reference counting to handle multiple users registering for the same event, but I'm planning on leveraging the multicast handling code for that. - Sean _______________________________________________ openib-general mailing list openib-general@openib.org http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
