187 * Otherwise, it will figure that fact out once it sees a LUN on the device
188 * that is greater than 0. If it is known up front that a device is a changer,

193 * your device hangs when it gets a 10 byte command. Adding a quirk just
194 * to get rid of the informative diagnostic message is not acceptable. All
195 * 10_BYTE_ONLY quirks must be documented in full in a PR (which should be
196 * referenced in a comment along with the quirk) , and must be approved by
197 * ken@FreeBSD.org. Any quirks added that don't adhere to this policy may
198 * be removed until the submitter can explain why they are needed.
199 * 10_BYTE_ONLY quirks will be removed (as they will no longer be necessary)
200 * when the CAM_NEW_TRAN_CODE work is done.
