It has not been tested on the\nMATSHITA or NEC variants -- the author only has access to the COMPAQ\nunit -- but the drives are functionally identical and the flag is a\nno-op on devices that do not exhibit the PDT 0x1f response. Drop or\nhold this patch if confirmation on real hardware is preferred before\nextending the quirk.\n\nSigned-off-by: Phil Pemberton \n---\n drivers/scsi/scsi_devinfo.c | 6 ++++--\n 1 file changed, 4 insertions(+), 2 deletions(-)","diff":"diff --git a/drivers/scsi/scsi_devinfo.c b/drivers/scsi/scsi_devinfo.c\nindex bfc2cbd43897..ab1ffa9433b7 100644\n--- a/drivers/scsi/scsi_devinfo.c\n+++ b/drivers/scsi/scsi_devinfo.c\n@@ -201,7 +201,8 @@ static struct {\n \t{\"LASOUND\", \"CDX7405\", \"3.10\", BLIST_MAX5LUN | BLIST_SINGLELUN},\n \t{\"Marvell\", \"Console\", NULL, BLIST_SKIP_VPD_PAGES},\n \t{\"Marvell\", \"91xx Config\", \"1.01\", BLIST_SKIP_VPD_PAGES},\n-\t{\"MATSHITA\", \"PD-1\", NULL, BLIST_FORCELUN | BLIST_SINGLELUN},\n+\t{\"MATSHITA\", \"PD-1\", NULL, BLIST_FORCELUN | BLIST_SINGLELUN |\n+\t\t\t\t BLIST_NO_LUN_1F},\n \t{\"MATSHITA\", \"DMC-LC5\", NULL, BLIST_NOT_LOCKABLE | BLIST_INQUIRY_36},\n \t{\"MATSHITA\", \"DMC-LC40\", NULL, BLIST_NOT_LOCKABLE | BLIST_INQUIRY_36},\n \t{\"Medion\", \"Flash XL MMC/SD\", \"2.6D\", BLIST_FORCELUN},\n@@ -212,7 +213,8 @@ static struct {\n \t{\"nCipher\", \"Fastness Crypto\", NULL, BLIST_FORCELUN},\n \t{\"NAKAMICH\", \"MJ-4.8S\", NULL, BLIST_FORCELUN | BLIST_SINGLELUN},\n \t{\"NAKAMICH\", \"MJ-5.16S\", NULL, BLIST_FORCELUN | BLIST_SINGLELUN},\n-\t{\"NEC\", \"PD-1 ODX654P\", NULL, BLIST_FORCELUN | BLIST_SINGLELUN},\n+\t{\"NEC\", \"PD-1 ODX654P\", NULL, BLIST_FORCELUN | BLIST_SINGLELUN |\n+\t\t\t\t BLIST_NO_LUN_1F},\n \t{\"NEC\", \"iStorage\", NULL, BLIST_REPORTLUN2},\n \t{\"NRC\", \"MBR-7\", NULL, BLIST_FORCELUN | BLIST_SINGLELUN},\n \t{\"NRC\", \"MBR-7.4\", NULL, BLIST_FORCELUN | BLIST_SINGLELUN},\n","prefixes":["v3","7/7"]}
