Heh! Be careful, we might be led into believing all this RCU is actually really rather simple and this complexity is a bug on your end ;-) > It records the grace-period number corresponding to > the quiescent state at the time of the quiescent state, which > works, but it seems better to simply erase any record of previous > quiescent states at the time that the CPU notices the new grace > period.

So why didn't you do that from the start? :-) That is, I'm curious to know some history, why was it so and what led you to this insight? -- 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/
