They seem to obscure things without much benefit. flags as bit positions generally only make sense if you use test/set/clear_bit, otherwise they just confuse things. And the accessors are pretty annoying, especially in the block layer. Trying to find the places where a BIO flag has an actual effect is pretty painful due to the mix of the different flags and the accessors. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
