I really don't want the multi-buffer nonsense proposed. An event gets _1_ buffer, that's it. That also means that if someone redirect another event into this buffer, it needs to just work. And because its a perf buffer, people expect it to look like one. So we've got 'wrap' it. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
