You have to walk to full node mapping for each array, but even with hundreds of nodes that should not be that costly (in the worst case you could create a small hash table for it in the kernel, but I'm not sure it's worth it) -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
