Subject: [dpdk-dev] [PATCH v2 04/14] eal: add EAL tailq list lock/unlock API
Date: Tue, 25 Jun 2019 17:05:16 +0100	[thread overview]
Message-ID: <cbf64d54d616b741d0261be53b5db4f2f606fb46.1561478388.git.anatoly.burakov@intel.com> (raw)
In-Reply-To: <cover.1561478388.git.anatoly.burakov@intel.com>
In-Reply-To: <cover.1561478388.git.anatoly.burakov@intel.com>

Currently, locking/unlocking the TAILQ list requires direct
access to the shared memory config. Add an API to do the same.
