  * @is_root: If 1, ignore the caller's permissions
  * @i_gh: An uninitialized holder for the new inode glock
  *
- * There will always be a vnode (Linux VFS inode) for the d_gh inode unless
- * @is_root is true.
+ * This can be called via the VFS filldir function when NFS is doing
+ * a readdirplus and the inode which its intending to stat isn't
+ * already in cache. In this case we must not take the directory glock
+ * again, since the readdir call will have already taken that lock.

  * Returns: errno
