Subject: [PATCH v2 07/10] scsi: libsas: Delete sas_ssp_task.task_prio
Since libsas was introduced in commit 2908d778ab3e ("[SCSI] aic94xx: new
driver"), sas_ssp_task.task_prio is never set, so delete it
and any references which depend on it being set (all of them).
Signed-off-by: John Garry <john.g.garry@...cle.com>
