    Subject[PATCH v2 10/27] compat_ioctl: ubd, aoe: use blkdev_compat_ptr_ioctl
    Date
    These drivers implement the HDIO_GET_IDENTITY and CDROMVOLREAD ioctl
    commands, which are compatible between 32-bit and 64-bit user space and
    traditionally handled by compat_blkdev_driver_ioctl().

    As a prerequisite to removing that function, make both drivers use
    blkdev_compat_ptr_ioctl() as their .compat_ioctl callback.
