Date: Fri, 10 May 2013 20:33:39 +0100 From: David Howells <dhowells@...hat.com> To: Trond.Myklebust@...app.com, torvalds@...ux-foundation.org Cc: linux-fsdevel@...r.kernel.org, linux-nfs@...r.kernel.org, linux-cachefs@...hat.com, linux-kernel@...r.kernel.org Subject: [PATCH 5/8] FS-Cache: Uninline fscache_object_init() [ver #2] Uninline fscache_object_init() so as not to expose some of the FS-Cache internals to the cache backend.
