Ho hum... :) Another way to approach that, and keep the volatile, is to have a "test_flags()" interface that takes the bit mask of values you want to test for cases where you know it is a single word flags value. The downside is that this kind of interface is easy to use incorrectly especially when accesses to the same flags use bot test_bit() and test_flags(). -- 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
