I think Tejun and I might be at a bit of an impasse with the ida rewrite itself, but I don't think there were any outstanding objections to the percpu ida code itself - and this is a standalone version. I was meaning to ask you Andrew, if you could take a look at the ida discussion and lend your opinion - I don't think there's any _specific_ technical objections left to my ida code, and it's now on a more philisophical "complexity vs. ..." level. -- 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/
