From 777be53463d763fdade82125db1afd25e365ca65 Mon Sep 17 00:00:00 2001 From: Benjamin Coddington Date: Tue, 24 Jan 2017 11:34:20 -0500 Subject: [PATCH] NFSv4.0: always send mode in SETATTR after EXCLUSIVE4 Some nfsv4.0 servers may return a mode for the verifier following an open with EXCLUSIVE4 createmode, but this does not mean the client should skip setting the mode in the following SETATTR. It should only do that for EXCLUSIVE4_1 or UNGAURDED createmode.
