Few C programmers like the goto statement. Without getting into the history of the goto (one of the longest and most famous controversies in computer programming), I'll summarize some of the reasons the goto is usually deprecated, but why the Linux kernel uses it anyway.
Any piece of code that uses goto can be rewritten without it. The use of goto statements can reduce the readability of the code, and make debugging harder, because at any position following a goto you can no longer derive unequivocally the conditions that led the execution to that point.
Let me make this analogy: given any node in a tree, you know what the path from the root to the node is. But if you add vines that entwine around branches randomly, you do not always have a unique path between the root and the other nodes ... (查看原文)
NETDEV_TX_OK*
The transmission succeeded. The buffer is not released yet (kfree_skb is not
issued). We will see in the section “Processing the NET_TX_SOFTIRQ: net_tx_
action” that the driver does not release the buffer itself but asks the kernel to do
so by means of the NET_TX_SOFTIRQ softirq. This provides more efficient memory
handling than if each driver did its own freeing. (查看原文)
