Description

At the bottom of mdt_mfd_open() we should test for MDS_FMODE_EXEC rather than FMODE_EXEC:

err_out:
        if (flags & FMODE_WRITE)
                        /* XXX We also need to close io epoch here.                       
                         * See LU-1220 - green */
                mdt_write_put(o);
        else if (flags & FMODE_EXEC)
                mdt_write_allow(o);
        return rc;
}
