Subject: [PATCH 11/11] pstore/ram: Add ECC support
Date: Fri, 11 May 2012 17:18:57 -0700 [thread overview]
Message-ID: <20120512001857.GK14782@lizard> (raw)
In-Reply-To: <20120512001506.GA8653@lizard>
This is now straightforward: just introduce a module parameter and pass
the needed value to persistent_ram_new().
