On a system with many SAS targets, it appears possible that a scsi_cmnd can time out without ever making it to the SAS LLDD or at the same time that a completion is occurring. In both of these cases, telling the LLDD to abort the sas_task makes no sense because the LLDD won't know about the sas_task; what we really want to do is to increase the timer. Note that this involves creating another sas_task bit to indicate whether or not the task has been sent to the LLDD; I could have implemented this by slightly redefining SAS_TASK_STATE_PENDING, but this way seems cleaner. This second version amends the aic94xx portion to set the TASK_AT_INITIATOR flag for all sas_tasks that were passed to lldd_execute_task. Signed-off-by: Darrick J.
