714  * scsi_rq_err_bytes - determine number of bytes till the next failure boundary
718  *     A request could be merge of IOs which require different failure
922 			 * if logging is enabled the failure will be printed
1107  * * BLK_STS_RESOURCE - if the failure is retryable
1108  * * BLK_STS_IOERR    - if the failure is fatal
2256  *	Returns zero if successful, or a negative error number on failure
2851  * Returns zero if successful or a negative error code upon failure.
2919  * Returns zero if successful or a negative error code upon failure.
2972  * Returns zero if successful or a negative error code upon failure.
3054  * Returns zero if successful or a negative error code upon failure.
3256  * Returns the length of the identification or error on failure.
3382  * Returns the identifier or error on failure.
