From e058f70b8070608fedfd3e39c2ead935beecb552 Mon Sep 17 00:00:00 2001 From: Steve Dickson Date: Wed, 22 May 2013 12:50:40 -0400 Subject: NFSv4: Introduce new label structure In order to mimic the way that NFSv4 ACLs are implemented we have created a structure to be used to pass label data up and down the call chain. This patch adds the new structure and new members to the required NFSv4 call structures. Signed-off-by: Matthew N.
