From a430607b2ef7c3be090f88c71cfcb1b3988aa7c0 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.
