Subject: [PATCH] perf tests: initialize sa.sa_flags
Date: Wed, 2 Mar 2016 12:55:22 +0000 [thread overview]
Message-ID: <1456923322-29697-1-git-send-email-colin.king@canonical.com> (raw)
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.
Signed-off-by: Colin Ian King <colin.king@canonical.com>
