This ioctl is used to set up RLE (read lock enabled) and WLE (write lock enabled) parameters of the Locking object. In Single User Mode (SUM), if the RangeStartRangeLengthPolicy parameter is set in the 'Reactivate' method, only Admin authority maintains the locking range length and start (offset) attributes of Locking objects set up for SUM. All other attributes from struct opal_user_lr_setup (RLE - read locking enabled, WLE - write locking enabled) shall remain in possession of the User authority associated with the Locking object set for SUM. With the IOC_OPAL_ENABLE_DISABLE_LR ioctl, the opal_user_lr_setup members 'range_start' and 'range_length' of the ioctl argument are ignored.
