Subject: [PATCH 09/11] perf tests: Initialize sa.sa_flags
Date: Wed, 2 Mar 2016 19:16:44 -0300 [thread overview]
Message-ID: <1456957006-3757-10-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1456957006-3757-1-git-send-email-acme@kernel.org>
From: Colin Ian King <colin.king@canonical.com>
The sa_flags field is not being initialized, so a garbage value is being
passed to sigaction. Initialize it to zero.
