Message-Id: <1461800683-25034-18-git-send-email-edumazet@google.com>
Date: Wed, 27 Apr 2016 16:44:43 -0700
From: Eric Dumazet <edumazet@...gle.com>
To: "David S . Miller" <davem@...emloft.net>

Subject: [PATCH net-next 17/17] net: snmp: kill STATS_BH macros
There is nothing related to BH in SNMP counters anymore,
since linux-3.0.
Rename helpers to use __ prefix instead of _BH prefix,
for contexts where preemption is disabled.
This more closely matches convention used to update
percpu variables.
