Subject: [PATCH 4.9 04/13] drm/msm: Ratelimit invalid-fence message
Date: Fri,  9 Apr 2021 11:53:24 +0200	[thread overview]
Message-ID: <20210409095259.772069495@linuxfoundation.org> (raw)
In-Reply-To: <20210409095259.624577828@linuxfoundation.org>

From: Rob Clark <robdclark@chromium.org>

[ Upstream commit 7ad48d27a2846bfda29214fb454d001c3e02b9e7 ]

We have seen a couple cases where low memory situations cause something
bad to happen, followed by a flood of these messages obscuring the root
cause.  Lets ratelimit the dmesg spam so that next time it happens we
don't lose the kernel traces leading up to this.
