From 94a6d75320b3681e6e728b70e18bd186cb55e682 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Tue, 22 Aug 2006 20:06:23 -0400 Subject: NFS: Use cached page as buffer for NFS symlink requests Now that we have a copy of the symlink path in the page cache, we can pass a struct page down to the XDR routines instead of a string buffer. Test plan: Connectathon, all NFS versions.
