Hi list,
as the rules on scsi_abort have changed again, I'd like to ask some questions.
The scsi_abort method is called in task context and may return
SCSI_ABORT_PENDING. It should not sleep. Is that right ?
Any queued srb should call the callback with DID_ABORT after scsi_abort.
Is that right ?
Can the middle layer cope with the callback called twice ?
Once with DID_OK/DID_ERROR and a second time with DID_ABORT.
There is a race in the driver that I cannot avoid causing this.
Is scsi_abort required to leave the device in a sane state ?
TIA
Oliver
