From: Yongseok Koh Date: Tue, 17 Apr 2018 18:39:14 +0000 (-0700) Subject: net/mlx4: fix alignment of memory region X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=96525b9e193139d11cabaaa6f27801bc636a447a;p=dpdk.git net/mlx4: fix alignment of memory region 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).
