[ofa-general] [PATCH] IB/mlx4: Use kzalloc when allocating a new mlx4_ib_qp

[Eli Cohen]

Current code uses kmalloc() and then does a bitwise or operation on
qp->flags at create_qp_common():

if (init_attr->create_flags & IB_QP_CREATE_BLOCK_MULTICAST_LOOPBACK)
                        qp->flags |= MLX4_IB_QP_BLOCK_MULTICAST_LOOPBACK;

Instead of taking care of clearing individual fields, just use kzalloc
and forget about similar problems in the future.
