-   Instructions for use
-   --------------------
-
-   1) Map a Linux block device to an existing OSD object.
-
-      In this example, we will use partition id 1234, object id 5678,
-      OSD device /dev/osd1.
-
-      $ echo "1234 5678 /dev/osd1" > /sys/class/osdblk/add
-
-
-   2) List all active blkdev<->object mappings.
-
-      In this example, we have performed step #1 twice, creating two blkdevs,
-      mapped to two separate OSD objects.
-
-      $ cat /sys/class/osdblk/list
-      0 174 1234 5678 /dev/osd1
-      1 179 1994 897123 /dev/osd0
-
-      The columns, in order, are:
-      - blkdev unique id
-      - blkdev assigned major
-      - OSD object partition id
-      - OSD object id
-      - OSD device
-
-
-   3) Remove an active blkdev<->object mapping.
-
-      In this example, we remove the mapping with blkdev unique id 1.
-
-      $ echo 1 > /sys/class/osdblk/remove
-
-
-   NOTE:  The actual creation and deletion of OSD objects is outside the scope
-   of this driver.
