[...] I'm glad the discussion seems to be slowly turning toward the event layering issues, but ... "markers being a userspace API"? That seems to be grossly misleading terminology. It's a kernel API like anything else being discussed here. What's different about it (vs. tracepoints) is that it could be one of the first clients of the unified ring buffer widget that concretely addresses the issue of encoding abstract traceworthy events into serialized data. (Of course, merging the lower level aspects of the marker/tracepoint implementations is all well and good.) - FChE -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
