[RFC PATCH 2/5] fuse: do not create cache for fuse request allocation

From: Mitsuo Hayasaka
Date: Thu Jul 05 2012 - 06:45:51 EST


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.
