In the quoted example, the effect of the activation switch is also documented by a comment. Of course we should restrain ourselves WRT the use of #if 0 ... #endif blocks in in-tree code, but sometimes they have sensible applications. -- Stefan Richter -=====-=-=== -=-= ---== http://arcgraph.de/sr/ - 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
