Re: [PATCH] netfilter: nft_counter: Fix reset of counters on 32bit archs

Agree. Thanks for the feedback.

On 32bit archs, you're definitely right. It would truncate the counter value on
32bit. However, the problem I intended to fix was the fact that, previously, a
negative value was passed to u64_stats_add() which always wrapped.

Initially, I was a bit reluctant to use s64 for u64_stats_sub() as I wanted to
keep the signature the same as the existing u64_stats_add(). As u64_stats_add()
is used in a lot of places, I was not sure about the effect of this.

However, I can prepare a v2 with just u64_stats_sub(u64_stats_t *, s64).
