From dcb9cda2ead34bbd44a02aa8197b3306f5b8ba02 Mon Sep 17 00:00:00 2001
From: Al Viro <viro@zeniv.linux.org.uk>
Date: Sun, 10 Jun 2012 18:05:36 -0400
Subject: [PATCH] don't pass nameidata to ->create()

boolean "does it have to be exclusive?" flag is passed instead;
Local filesystem should just ignore it - the object is guaranteed
not to be there yet.
