From de53c52f9d9317986b7ad69c8cca2d8554201354 Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Tue, 22 Nov 2016 14:44:17 +0100 Subject: netfilter: x_tables: pass xt_counters struct instead of packet counter commit 4d31eef5176df06f218201bc9c0ce40babb41660 upstream. On SMP we overload the packet counter (unsigned long) to contain percpu offset. Hide this from callers and pass xt_counters address instead. Preparation patch to allocate the percpu counters in page-sized batch chunks.
