From 7b4b2fa37587394fb89fa51a4bea0820a1b37a5d Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Fri, 4 Jun 2021 12:27:06 +0200 Subject: netfilter: annotate nf_tables base hook ops This will allow a followup patch to treat the 'ops->priv' pointer as nft_chain argument without having to first walk the table/chains to check if there is a matching base chain pointer.
