Let's save the original setting of the "port=" mount option in the mount's nfs_server structure. This allows us to simplify the default behavior of port setting for NFSv4 mounts: by default, NFSv2/3 mounts first try an RPC bind to determine the NFS server's port, unless the user specified the "port=" mount option; Users can force the client to skip the RPC bind by explicitly specifying "port=". NFSv4, by contrast, assumes the NFS server port is 2049 and skips the RPC bind, unless the user specifies "port=". Users can force an RPC bind for NFSv4 by explicitly specifying "port=0". I added a couple of extra comments to clarify this behavior. Signed-off-by: Chuck Lever Cc: Miklos Szeredi Signed-off-by: Trond Myklebust --- Reading git-diff-tree failed
