In other words, mass distributed RCU stress-testing by stealth ;-) I'll make it default-off once the RCU related changes have calmed down. The rcutorture kernel threads run at nice +19 so they should be barely noticeable. (except for a sudden and unexplained spike in the world's power consumption, and the resulting energy crisis ;-) 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/
