[PATCH] knfsd: Allow max size of NFSd payload to be configured
The max possible is the maximum RPC payload. The default depends on amount of total memory. The value can be set within reason as long as no nfsd threads are currently running. The value can also be ready, allowing the default to be determined after nfsd has started.
