Bug is the packet producer, not in try_to_coalesce() This issue comes up on netdev from times to times... The WARN_ON() in try_to_coalesce() is an attempt to detect a producer made a lie about truesize, leading to OOM in case of abuses. Do not paper over the bug, find the root cause and fix it, thanks. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
