You're right. Since scmd remains valid until blk_mq_free_request() is
called in the task work callback, we can extract all status information
directly from scmd->result in scsi_bsg_uring_task_cb() instead of storing
it in the PDU. This approach is cleaner and follows your suggestion to
read from scmd->result directly.

Done. Removed all unnecessary " & 0xff" from u8 expressions.

Done. Using status_byte() macro instead of open-coding
(scmd->result & 0xff).
Will include these changes in v7.
