[dpdk-users] Integration from Dpdk18.05 to Dpdk19.11 - rte_timer_subsystem_init(void)

[Li, Jiu (NSB - CN/Hangzhou)]

Hello!  Dpdk experts,

On Dpdk 18.05,  void rte_timer_subsystem_init(void)
On Dpdk 19.11,  int    rte_timer_subsystem_init(void) implementation changed, which will return 0, -EALREADY or -ENOMEM;

There is still have  dpdk "process" mode (instead of pdkd thread mode) deployment in my side.
Can I have a question?

If rte_timer_subsystem_init() is called one time is enough?
After rte_timer_subsystem_init() called with return 0 by one process , then other processes are able to use "rte timer" service without issue, right?

Thanks in advance!

Best Regards.
