I'm seeing it fail on ppc as well (64k pages), with older RHEL7 kernels:

block/ioctl.c:
        case BLKRASET:
        case BLKFRASET:
                if(!capable(CAP_SYS_ADMIN))
                        return -EACCES;
                bdev->bd_bdi->ra_pages = (arg * 512) / PAGE_SIZE;
                return 0;
