Wrong intendation.
It should be ok. That line is for the QUEUE_FLAG_WC test. We end up with:
op = REQ_OP_WRITE;
if (test_bit(QUEUE_FLAG_FUA, &q->queue_flags)) {
if (cmd->se_cmd_flags & SCF_FUA)
op_flags = WRITE_FUA;
else if (!test_bit(QUEUE_FLAG_WC, &q->queue_flags))
op_flags = WRITE_FUA;
}
Indeed, you are correct.
