Subject: [dpdk-dev] [PATCH 2/2] net/mlx4: fix alignment of Memory Region
Date: Tue, 17 Apr 2018 11:39:14 -0700 [thread overview]
Message-ID: <20180417183914.10175-2-yskoh@mellanox.com> (raw)
In-Reply-To: <20180417183914.10175-1-yskoh@mellanox.com>
The memory region is [start, end), so if the memseg of 'end' isn't
allocated yet, the returned memseg will have zero entries and this will
make 'end' zero (nil).
Fixes: c2fe5823224a ("net/mlx4: use virt2memseg instead of iteration")
