From af32f8cb559748adc106e1e2e118109231eb6954 Mon Sep 17 00:00:00 2001 From: rmacklem Date: Tue, 21 Jun 2011 19:58:29 +0000 Subject: [PATCH] Fix the new NFSv4 server so that it checks for VREAD_ACL when a client does a Getattr for an ACL and not VREAD_ATTRIBUTES. This was found during the recent NFSv4 interoperability Bakeathon.
