sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/vdev_impl.h:
    Add two offset/lba based AVL trees to the vdev queue
    object.

sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/zio.h:
    Add a second AVL node within each ZIO so that vdev_queue.c
    can sort ZIOs by both type and priority.

sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev_queue.c:
    Combine reads and writes, irrespecitve of their priorities
    into unified, offset sorted, trees.  Selection of the
    ZIO to issue is unchanged, but aggregation now uses the
    unified tree of the appropriate type so that aggregation
    across priority classes is possible.
