A bind mount doesn't actually want us to set up OPEN state on the NFSv4 server and return a fully initialised 'struct file' in the struct nameidata. If it did, we would already have set the LOOKUP_OPEN flag together with the accompanying open intent structure in the struct nameidata. Ditto for the quotactl().
