<div class="textblock"><p>This example implements a file system with two files:</p><ul>
<li>'current-time', whose contents change dynamically: it always contains the current time (same as in notify_inval_inode.c).</li>
<li>'growing', whose size changes dynamically, growing by 1 byte after each update. This aims to check if cached file metadata is also invalidated.</li>
</ul>
