We're just papering over the real problem, which is making sure all dangling references to something really go away when we release/unload an object. Point it to a dummy set of ops and do a synchronize_net() or similar. I'm not applying this patch, sorry. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
