From d706ed1f50d3f7fae61a177183562179abe8e4bb Mon Sep 17 00:00:00 2001 From: Stanislav Kinsbursky Date: Mon, 26 Dec 2011 15:43:49 +0300 Subject: [PATCH] SUNPRC: cleanup RPC PipeFS pipes upcall interface RPC pipe upcall doesn't requires only private pipe data. Thus RPC inode references in this code can be removed.
