Some of the things we are trying to improve upon are things that are better supported in 2.6. Some differences:
- We will support controller hotplug. - We allow any type of device (dm, scsi, ide, LVM@ etc) as storage. And we do not want hook into SCSI-ml's upper layer drivers and deal with that refcounting if we can help it so we push a lot of code to userspace and only do reads and writes in the kernel. - We also hope to support any block layer target. - As mentioned before, scatterlists by using the block layer's support.
There may be more that I am forgetting, but originally we started out by trying to clean up the SCST code for 2.6 and make it resemble SCSI-ml's hotplug model. As we did this it looked like some code could live in userspace and it would end up being a rewrite becuase there was so much to do so we started a new project. We hope to work with Vlad and the SCST developers. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
