Subject: [PATCH AUTOSEL 5.11 05/12] pstore/ram: Rate-limit "uncorrectable error in header" message
Date: Sun, 7 Mar 2021 08:57:39 -0500 [thread overview]
Message-ID: <20210307135746.967418-5-sashal@kernel.org> (raw)
In-Reply-To: <20210307135746.967418-1-sashal@kernel.org>
From: Dmitry Osipenko <digetx@gmail.com>
[ Upstream commit 7db688e99c0f770ae73e0f1f3fb67f9b64266445 ]
There is a quite huge "uncorrectable error in header" flood in KMSG
on a clean system boot since there is no pstore buffer saved in RAM.
Let's silence the redundant noisy messages by rate-limiting the printk
message. Now there are maximum 10 messages printed repeatedly instead
of 35+.
