> Subject: [dpdk-dev] [PATCH] net/mlx4: fix memory region cleanup routine
>
> mlx4 driver has a global list of Memory Regions created by device, and there
> is a ml4_mr_release() routine which makes a memory cleanup at device
> closing. The head of device MR list was fetched outside the rwlock protected
> section. Also some noticed typos are fixed.
