[PATCH -v2 2/6] fuse: make the maximum read/write request size tunable

to connect cloud storage services and distributed filesystems. Larger data might be stored in them over networking via FUSE and the overhead might affect the read/write throughput. So, a tunable functionality of read/write request size is useful. Signed-off-by: Mitsuo Hayasaka Cc: Miklos Szeredi Cc

[PATCH -v2 3/6] fuse: remove cache for fuse request allocation

Remove fuse_req_cachep, which was used for fuse request buffer. It is no longer used since the buffer is allocated dynamically due to the tunable maximum read/write request size. Signed-off-by: Mitsuo Hayasaka Cc: Miklos Szeredi Cc: Nikolaus Rath Cc: Liu Yuan Cc: Has-Wen Nienhuys --- fs
