Yes. I would appreciate backporting it all the way where the code is
available. The dependencies
1eacdd71b3436 ("netfilter: nft_counter: Disable BH in nft_counter_offload_stats().")
a0b39e2dc7017 ("netfilter: nft_counter: Synchronize nft_counter_reset() against reader.")
were already routed via stable.
The problem is that the seqcount has no lock associated so a reader
could preempt a writer and then lockup spinning.
