Subject: [PATCH v3 8/9] pstore: max out console log level during sysfs dump switch
Date: Thu, 18 Oct 2012 14:06:06 +0300 [thread overview]
Message-ID: <1350558367-31801-9-git-send-email-dragos.tatulea@intel.com> (raw)
In-Reply-To: <1350558367-31801-1-git-send-email-dragos.tatulea@intel.com>
From: Dragos Tatulea <dragos.tatulea@intel.com>
Otherwise we might miss out on some pstore dumpers that use
printks below current log level.
