Subject: [PATCH 10/14] backport: update u64_stats_init() to a new version in kernels < 4.2
Date: Thu, 20 Sep 2018 14:28:38 +0300
Message-ID: <20180920112842.27198-11-luca@coelho.fi> (raw)
In-Reply-To: <20180920112842.27198-1-luca@coelho.fi>

From: Luca Coelho <luciano.coelho@intel.com>

The u64_stats_init() macro was turned into a static inline function in
v4.2 to prevent warnings that happen when its argument is not used
elsewhere.

Since we started hitting these warnings, undefine the macro and define
the static inline to prevent them.
