Saeed Mahameed says: ==================== Mellanox, mlx5 fixes 2019-05-28 This series introduces some fixes to mlx5 driver. Please pull and let me know if there is any problem. For -stable v4.13: ('net/mlx5: Allocate root ns memory using kzalloc to match kfree') For -stable v4.16: ('net/mlx5: Avoid double free in fs init error unwinding path') For -stable v4.18: ('net/mlx5e: Disable rxhash when CQE compress is enabled') ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
