AFAIK hlist_add_head is a function to add a node at first position in collision chain at particular head ( hash bucket )<br><br>For ex. whenever a new inode is allocated the hash value of that inode is calculated which acts as an index in inode_hashtable<br>
which subsequently provides and hash bucket ( head ) for that inode. Now this inode attached at the first position in collision chain for the calculated hash bucket pushing the current first inode to second position.<br>
<br>
For further clarification have a look at inode_add_to_lists() and __inode_add_to_lists() functions.<br><br>Regards,<br><font color="#888888">Piyush</font><div><div></div><div class="h5"><br><br><div class="gmail_quote">On Tue, Jun 28, 2011 at 8:05 PM, luca ellero <span dir="ltr"><<a href="mailto:lroluk@gmail.com" target="_blank">lroluk@gmail.com</a>></span> wrote:<br>

can someone please explain what is the role of hlist_add_head (used in<br>
in hash lists). Or maybe provide some links with good examples of its<br>
use. I had a look at fs/dcache.c but frankly I can't understand it very<br>
well.<br>
Thanks in advance<br>
