I don't think you understand the point. A non-Plextor device could have a HALT AND CATCH FIRE command on that opcode. That definitely wouldn't be safe. If 'just a read command' were enough, we wouldn't need to have filtering for read commands at all. > Plextor users have been waiting a long time for the features in linux, so > please think about a solution which is a solution for all users. The only solutions I can think of are big and ugly if they're in the kernel. Why not write a set-uid helper that checks the device manufacturer and device type, then issues the appropriate command? That would work on 2.4 as well as 2.6. - : 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
