I'm not seeing it at all here as my SSD apparently does implement the caching mode page. I can see that it is emitted by sd_read_cache_type(), which is called by sd_revalidate_disk(), and that is apparently now called 3 times during probe. Which is quite ridiculous. And I wonder whether this situation (no caching mode page) is really serious enough to deserve logging at ERR severity? Ben. -- Ben Hutchings Logic doesn't apply to the real world. - Marvin Minsky
