At this point in the patch series I agree, but in later patches we take advantage of nd bus services. "[PATCH 15/21] nd: pmem label sets and namespace instantiation" adds support for labeled pmem namespaces, and in "[PATCH 19/21] nd: infrastructure for btt devices" we make pmem capable of hosting btt instances. -- 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/

I don't think there is any need to move the driver around. Also please split the addition of the ida allocation from adding the new probe methods. -- 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/
