From 132f97715c098393fb8de3c26b07b9fdbd2334f1 Mon Sep 17 00:00:00 2001 From: Ricardo Labiaga Date: Thu, 10 Sep 2009 12:26:12 +0300 Subject: [PATCH] nfsd41: Backchannel: Add sequence arguments to callback RPC arguments Follow the model we use in the client. Make the sequence arguments part of the regular RPC arguments. None of the callbacks that are soon to be implemented expect results that need to be passed back to the caller, so we don't define a separate RPC results structure. For session validation, the cb_sequence decoding will use a pointer to the sequence arguments that are part of the RPC argument.
