6   Returns true if the dentry represents a name that maps to an inode
7   (ie. -&gt;d_inode is not NULL).  The dentry might still represent a whiteout if

11   Note!  (1) This should be used *only* by a filesystem to examine its own
12   dentries.  It should not be used to look at some other filesystem's
13   dentries.  (2) It should also be used in combination with <code class="function">d_inode</code> to get
14   the inode.
