17  * Perform basic GET LOG PAGE commands just to prove that this works end to
18  * work. This is not intended to be an exhaustive set of tests, merely proving
19  * that things work. We utilize the SMART / Health information and the Firmware
20  * Slot information because these two pages have existed since NVMe 1.0 and both
21  * are the same fixed size (512 bytes). They both have useful pieces of expected
22  * non-zero data: the current temperature and firmware slot respectively. These
23  * are both within the first u32, so we just check that the entire u32 is
24  * non-zero and not all 1s.
25  *
26  * It's quite probably virtualized devices will lie about these. When they do,
27  * we should add specific devices to an exception list.
