AFAIK hlist_add_head is a function to add a node at first position in collision chain at particular head ( hash bucket ) For ex. whenever a new inode is allocated the hash value of that inode is calculated which acts as an index in inode_hashtable 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. For further clarification have a look at inode_add_to_lists() and __inode_add_to_lists() functions. Regards, Piyush On Tue, Jun 28, 2011 at 8:05 PM, luca ellero [off-list ref] wrote:quoted
Hi everybody, can someone please explain what is the role of hlist_add_head (used in in hash lists). Or maybe provide some links with good examples of its use. I had a look at fs/dcache.c but frankly I can't understand it very well. Thanks in advance Luca _______________________________________________ Kernelnewbies mailing list Kernelnewbies at kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
