Message-ID: <20130503003335.14952.45228.stgit@warthog.procyon.org.uk>
Date: Fri, 03 May 2013 01:33:35 +0100
From: David Howells <dhowells@...hat.com>
To: linux-cachefs@...hat.com
Cc: linux-fsdevel@...r.kernel.org, linux-nfs@...r.kernel.org,

linux-kernel@...r.kernel.org
Subject: [PATCH 4/8] FS-Cache: Uninline fscache_object_init()
Uninline fscache_object_init() so as not to expose some of the FS-Cache
internals to the cache backend.
