[dpdk-dev] Are there considerations about resource recycling by the process, not by the OS?

[Tetsuya.Mukawa]

Hi Zhangkun,

Do you talk about resource management of DPDK when a process is finished?
If so, I guess DPDK doesn't care so much about freeing resources once
allocated by the process.
For example, there is no function to free a mempool.

Thanks,
Tetsuya
