+Subject: smb3: directory sync should not return an error
+
+From: Steve French <smfrench@gmail.com>
+
+commit 6e70c267e68d77679534dcf4aaf84e66f2cf1425 upstream.
+
+As with NFS, which ignores sync on directory handles,
+fsync on a directory handle is a noop for CIFS/SMB3.
+Do not return an error on it.  It breaks some database
+apps otherwise.
