Subject: NFS: Create a common rpc_call_ops struct
X-Git-Tag: omap-for-v3.16/fixes-against-rc1~64^2~39
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6f92fa4581f1c26562f80dc686b3c9ea76556911;p=pandora-kernel.git

NFS: Create a common rpc_call_ops struct

The read and write paths set up this struct in exactly the same way, so
create a single shared struct.
