From: Benjamin Coddington <bcodding@xxxxxxxxxxxxxxxxxx>
Now that we have umask support, we shouldn't re-send the mode in a SETATTR
following an exclusive CREATE, or we risk having the same problem fixed in
commit 5334c5bdac92 ("NFS: Send attributes in OPEN request for
NFS4_CREATE_EXCLUSIVE4_1"), which is that files with S_ISGID will have that
bit stripped away.
