Date: Thu, 05 Jul 2012 19:50:50 +0900 From: Mitsuo Hayasaka <mitsuo.hayasaka.hu@...achi.com> To: Miklos Szeredi <miklos@...redi.hu> Cc: fuse-devel@...ts.sourceforge.net, linux-kernel@...r.kernel.org, linux-doc@...r.kernel.org, yrl.pp-manager.tt@...achi.com, Mitsuo Hayasaka <mitsuo.hayasaka.hu@...achi.com>, Miklos Szeredi <miklos@...redi.hu> Subject: [RFC PATCH 2/5] fuse: do not create cache for fuse request allocation The fuse_req_cachep was used for request allocation in fuse. This patch does not create it since it is not used anymore due to the tunable read/write request size in fuse.
