ftrace's __print_symbolic() has a (very poorly documented) requirement that any enum values used in the symbol to string translation table be wrapped in a TRACE_DEFINE_ENUM so that the enum value can be encoded in the ftrace ring buffer. Fix this unsatisfied requirement. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Eric Sandeen <sandeen@redhat.com>
