nfs: Authentication performance improvements
When file operations are sent to the NFS server, authorized filehandles are cached using the exportid, mountid, gfid and host as the key to the cache. This meant that any file OR directory will always fail on the *first* fop to that filehandle since the cache used the gfid as part of the key to the cache. However, if an export is authorized, this effectively means that ALL subdirectories and files in the export directory are authorized per the permissions of the export. This results slow times to walking a directory structure over an NFS mount.
