charset="utf-8" Precedence: bulk X-Mailing-List: linux-kernel@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 Content-Transfer-Encoding: 8bit Running the tests continuously I noticed that sometimes the sigpipe test would fail due to a race between the control message of the test and the vsock transport messages. While I was at it I also improved the test by checking the errno we expect.
