Mikulas Patocka fd1232b214 sym53c8xx_2: Set DID_REQUEUE return code when aborting squeue ... This patch fixes I/O errors with the sym53c8xx_2 driver when the disk returns QUEUE FULL status. When the controller encounters an error (including QUEUE FULL or BUSY status), it aborts all not yet submitted requests in the function sym_dequeue_from_squeue. This function aborts them with DID_SOFT_ERROR. If the disk has full tag queue, the request that caused the overflow is aborted with QUEUE FULL status (and the scsi midlayer properly retries it until it is accepted by the disk), but the sym53c8xx_2 driver aborts the following requests with DID_SOFT_ERROR --- for them, the midlayer does just a few retries and then signals the error up to sd. The result is that disk returning QUEUE FULL causes request failures. The error was reproduced on 53c895 with COMPAQ BD03685A24 disk (rebranded ST336607LC) with command queue 48 or 64 tags. The disk has 64 tags, but under some access patterns it return QUEUE FULL when there are less than 64 pending tags. The SCSI specification allows returning QUEUE FULL anytime and it is up to the host to retry.
