This looks very much like the CONFIG_PREEMPT problem in not so extreme form. Maybe we need to add another config option:
CONFIG_REALLY_REALLY_NO_PREEMPT to get the fastest code possible and those cond_rescheds removed from the critical paths? Or better CONFIG_PREEMPT_HALF_WAY to enable those cond_rescheds. -- 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/
