Otherwise: 1/ we do not honor the libata specific restrictions on the queue depth 2/ libsas drivers that do not set sdev->tagged_supported are unable to change the queue_depth of ata devices via sysfs Cc: Tejun Heo <tj@xxxxxxxxxx> Cc: Xiangliang Yu <yuxiangl@xxxxxxxxxxx> Cc: Jack Wang <jack_wang@xxxxxxxxx> Cc: Mark Salyzyn <msalyzyn@xxxxxxxxxxxxxx> Signed-off-by: Dan Williams <dan.j.williams@xxxxxxxxx> --- drivers/ata/libata-core.c | 1 + drivers/ata/libata-scsi.c | 44 +++++++++++++++++++++++------------ drivers/scsi/libsas/sas_scsi_host.c | 11 ++++++++- include/linux/libata.h | 2 ++ 4 files changed, 42 insertions(+), 16 deletions(-) ______________________________________________________________________ This email may contain privileged or confidential information, which should only be used for the purpose for which it was sent by Xyratex.
