SUNRPC: Parametrize how much of argsize should be zeroed
[ Upstream commit 103cc1fafee48adb91fca0e19deb869fd23e46ab ]
Currently, SUNRPC clears the whole of .pc_argsize before processing
each incoming RPC transaction. Add an extra parameter to struct
svc_procedure to enable upper layers to reduce the amount of each
operation's argument structure that is zeroed by SUNRPC.
The size of struct nfsd4_compoundargs, in particular, is a lot to
clear on each incoming RPC Call. A subsequent patch will cut this
down to something closer to what NFSv2 and NFSv3 uses.
This patch should cause no behavior changes.
