Hi,Ferruh,
Thanks, and I will fix it.
Since both the following two patches[1][2](in different patchsets) uses
__atomic_XXX,
I will keep using __atomic_XX in the patches first.
After the two patches are accepted, resend the fixed patch[3]
and change all __atomic_XX to rte_atomic_XXX.
[1][PATCH] net/hns3: fix VF multiple count on one reset
[2][PATCH] net/hns3: refactor handle mailbox function
[3][PATCH] net/hns3: use stdatomic API
Best regards,
Jie Hai
