So right now 2.4 is useless to anyone with an M/O drive. It wasn't deliberately ripped out, it just vanished when Eric started his SCSI rewrite in 2.3 :-). For 2.5 I would really like the change mentioned earlier -- make sure that no block drivers should have to deal with any request for smaller sector sizes than their hw sector size. For 2.4, I guess I can apply much the same fix for MO as I did for CD-ROM. -- * Jens Axboe * SuSE Labs - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
