Thanks for your changes Francesco. Funny, checkpatch doesn't detect braces were used for single-line instructions. Generally it looks fine :) I still would like to take a look at this solution in comparison to single worker. So let me repeat me request: do you still have patch implementing 1 worker solution? Could you share it? -- Rafał -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
