From 4a0dee1ffe0e8f4101e704a325e97f8997b0abcc Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Tue, 1 Aug 2017 12:11:12 -0700 Subject: [PATCH] netvsc: Initialize 64-bit stats seqcount On 32-bit hosts and with CONFIG_DEBUG_LOCK_ALLOC we should be seeing a lockdep splat indicating this seqcount is not correctly initialized, fix that. In commit 6c80f3fc2398 ("netvsc: report per-channel stats in ethtool statistics") netdev_alloc_pcpu_stats() was removed in favor of open-coding the 64-bits statistics, except that u64_stats_init() was missed.
