It might get constrictive after a while. please talk to John and Thomas about GTOD interfaces. Right now the solution used by the latency tracer is working out pretty OK - but if something better comes along i can use that too. It's not a burning issue though, unless you know of some bug. (i'm not sure what you mean by it becoming constrictive) Ingo - 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/ | ||||||||||||
