Then write better questions "Why?" isn't very useful. > Why doesn't bsg support sg v3 commands? You should know, the discussion on that happened at the storage summit and on linux-scsi. It was decided to drop sg v3 support from bsg, and only focus on making bsg the driver for sg v4 commands. As you know, we already have dual paths for sg v3. For sg v4 we can get rid of that pain, and just have a single driver for handling that. -- Jens Axboe - 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
