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. Fixes: 5334c5bdac92 ("NFS: Send attributes in OPEN request for NFS4_CREATE_EXCLUSIVE4_1") Signed-off-by: Benjamin Coddington <bcodding@redhat.com> Cc: stable@vger.kernel.org # v4.3+ Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
