> From: Zhichao Zeng <[email protected]>

> The eal-intr-thread is not closed before memory cleanup in the process of

> This patch close the eal-intr-thread before memory cleanup when exiting to
> avoid segment fault. And add some atomic operations to avoid executing
> rte_eal_cleanup in the child process spawned by fork() in some test > cases,
> e.g. debug_autotest of dpdk-test.
