The existence of VPD page B9h indicates if a device has multiple concurrent positioning ranges. The page content describes each range supported by the device. sd_read_cpr() is called from sd_revalidate_disk() and uses the block layer functions disk_alloc_independent_access_ranges() and disk_set_independent_access_ranges() to represent the set of actuators of the device as independent access ranges. The format of the Concurrent Positioning Ranges VPD page B9h is defined in section 6.6.6 of SBC-5. Signed-off-by: Damien Le Moal Reviewed-by: Hannes Reinecke Reviewed-by: Martin K.
