I think it would be counted in the child process when 'fork()' is called,
and in the parent process, it would be zero.

Thanks for your advice.

Yes. But in some case(e.g. debug_autotest of dpdk-test), it would fork
a child process to test 'rte_exit()', then it would call 'rte_eal_cleanup()'.
So 'is_forked' is introduced to avoid this situation.
