Subject: [PATCH 3.10 31/53] axonram: Fix bug in direct_access
Date: Tue, 3 Mar 2015 22:06:34 -0800 [thread overview]
Message-ID: <20150304054615.230844689@linuxfoundation.org> (raw)
In-Reply-To: <20150304054609.869052846@linuxfoundation.org>
3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matthew Wilcox <matthew.r.wilcox@intel.com>
commit 91117a20245b59f70b563523edbf998a62fc6383 upstream.
The 'pfn' returned by axonram was completely bogus, and has been since
2008.
