Subject: [PATCH v3 85/85] NFSD: Remove macros that are no longer used
Date: Mon, 23 Nov 2020 15:11:26 -0500
Message-ID: <160616228617.51996.12808577536167674350.stgit@klimt.1015granger.net> (raw)
In-Reply-To: <160616177104.51996.14915419165992024951.stgit@klimt.1015granger.net>

Now that all the NFSv4 decoder functions have been converted to
make direct calls to the xdr helpers, remove the unused C macros.
