> Subject: [PATCH v2 2/4] eventdev: use c11 atomics for lcore timer armed flag
>
> The in_use flag is a per core variable which is not shared between lcores in
> the normal case and the access of this variable should be ordered on the
> same core. However, if non-EAL thread pick the highest lcore to insert timers
> into, there is the possibility of conflicts on this flag between threads. Then
> the atomic CAS operation is needed.
>
> Use the c11 atomic CAS instead of the generic rte_atomic operations to avoid
> the unnecessary barrier on aarch64.
