> Subject: [PATCH v2 00/17] use __atomic operations returning previous value
>
> This series replaces uses of __atomic_{add,and,or,sub,xor}_fetch with
> __atomic_fetch_{add,and,or,sub,xor} intrinsics. The latter omits generation
> of code that
> is only needed if the returned value is actually used.
>
> Additionally, this change simplifies adapting dpdk to standard atomics
> planned for 23.07
> since __atomic_fetch_xxx can be trivially replaced with atomic_fetch_xxx
> whereas
> __atomic_xxx_fetch has no standard equivalent.
>
>
> v2:
> net/iavf patch had one incorrect change to __atomic_fetch_sub
> from __atomic_sub_fetch the new value was assigned to a variable
> on the previous line so revert the change from the patch.
