asd_abort_task – ABORT TASK TMF : the task to be aborted
Before calling ABORT TASK the task state flags should be ORed with SAS_TASK_STATE_ABORTED (unless SAS_TASK_STATE_DONE is set) under the task_state_lock IRQ spinlock, then ABORT TASK must be called.
Implements the ABORT TASK TMF, I_T_L_Q nexus. Returns: SAS TMF responses (see sas_task.h), -ENOMEM, -SAS_QUEUE_FULL.
When ABORT TASK returns, the caller of ABORT TASK checks first the task->task_state_flags, and then the return value of ABORT TASK.
If the task has task state bit SAS_TASK_STATE_DONE set, then the task was completed successfully prior to it being aborted. The caller of ABORT TASK has responsibility to call task->task_done() xor free the task, depending on their framework. The return code is TMF_RESP_FUNC_FAILED in this case.
Else the SAS_TASK_STATE_DONE bit is not set, If the return code is TMF_RESP_FUNC_COMPLETE, then the task was aborted successfully. The caller of ABORT TASK has responsibility to call task->task_done() to finish the task, xor free the task depending on their framework. else the ABORT TASK returned some kind of error. The task was not cancelled. Nothing can be assumed. The caller of ABORT TASK may wish to retry.

asd_invalidate_edb – invalidate an EDB and if necessary post the ESCB : pointer to Empty SCB : index [0,6] to the empty data buffer which is to be invalidated
After an EDB has been invalidated, if all EDBs in this ESCB have been invalidated, the ESCB is posted back to the sequencer. Context is tasklet/IRQ.

asd_query_task – send a QUERY TASK TMF to an I_T_L_Q nexus task: pointer to sas_task struct of interest
Returns: TMF_RESP_FUNC_COMPLETE if the task is not in the task set, or TMF_RESP_FUNC_SUCC if the task is in the task set.
Normally the management layer sets the task to aborted state, and then calls query task and then abort task.
