Subject: [PATCH] vsock: ratelimit unknown ioctl error message
Date: Fri, 23 Oct 2020 13:21:13 +0100 [thread overview]
Message-ID: <20201023122113.35517-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
When exercising the kernel with stress-ng with some ioctl tests the
"Unknown ioctl" error message is spamming the kernel log at a high
rate. Rate limit this message to reduce the noise.
