* The code figures out how many entries the sk_buff will require in the
1663
1663
* cmdQ and updates the cmdQ data structure with the state once the enqueue
1664
1664
* has complete. Then, it doesn't access the global structure anymore, but
1666
1666
* around that code, we can make the function reentrant without holding the
1667
1667
* lock when we actually enqueue (which might be expensive, especially on
1668
1668
* architectures with IO MMUs).
