Subject: [PATCH 2/2] baseband/fpga_lte_fec: use new barrier API
Date: Thu, 22 Feb 2024 17:21:13 +0100	[thread overview]
Message-ID: <20240222162113.1896370-2-maxime.coquelin@redhat.com> (raw)
In-Reply-To: <20240222162113.1896370-1-maxime.coquelin@redhat.com>

rte_smp_rmb() is deprecated, use the new API instead as
suggested in rte_atomic header.
