From 4eba8b78e1390f46828e00d6fa4d651c3d219894 Mon Sep 17 00:00:00 2001 From: Liping Zhang Date: Sat, 18 Feb 2017 10:35:47 +0800 Subject: netfilter: nfnetlink: remove static declaration from err_list Otherwise, different subsys will race to access the err_list, with holding the different nfnl_lock(subsys_id). But this will not happen now, since ->call_batch is only implemented by nftables, so the err_list is protected by nfnl_lock(NFNL_SUBSYS_NFTABLES).
