I also point out that handling disk partitions as a -tiny- remapping blkdev also has the advantage of making it easy to have a single request device per hardware device (a simple remap shouldn't require its own request queue, right?), while remapping devices flexibility to do their own request queue management.

think of the simplifications possible, when partitions are just another block device, just like anything else... No special partitions arrays in the lowlevel blkdev, etc. - 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/
