    selftests: drivers/s390x: Add uvdevice tests · cbac9242
    Steffen Eiden authored
    Adds some selftests to test ioctl error paths of the uv-uapi.
    The Kconfig S390_UV_UAPI must be selected and the Ultravisor facility
    must be available. The test can be executed by non-root, however, the
    uvdevice special file /dev/uv must be accessible for reading and
    writing which may imply root privileges.
