Ok, found the culprit, now to figure out the motive and fix it. ib_srp's srp_cleanup_module calls srp_release_transport(), which calls transport_container_unregister() for the rport_attr_cont member of struct srp_internal. That last unregister call is returning -EBUSY, but it gets ignored, and the list node gets erased (or just reused) when the module's text/memory is free'd. Now, to see if ib_srp should be waiting for everything to be destroyed before calling srp_release_transport(), or if it is just not removing some attributes properly. That's a next week thing if no one beats me to it. _______________________________________________ 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
