The userspace library calls mlock() and then the kernel does get_user_pages().

The API for uverbs memory registration is ibv_reg_mr(), and right now the memory is pinned and that's it. - R. _______________________________________________ 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
