13   Search for the inode specified by <em class="parameter"><code>hashval</code></em> and <em class="parameter"><code>data</code></em> in the inode cache.
14   If the inode is in the cache, the inode is returned with an incremented
15   reference count.

17   I_NEW is not waited upon so you have to be very careful what you do
18   with the returned inode.  You probably should be using <code class="function">ilookup5</code> instead.

20   <em class="parameter"><code>test</code></em> is called with the inode_hash_lock held, so can't sleep.
