I am trying to obtain file name at block layer level (above IO scheduler). At this level I receive bio structure, within which page pointers are kept. Thereby I do following to obtain the inode and dentry - struct inode *inode_ptr = page->mapping->host; if (inode_ptr != NULL) /* Access dentry i.e. i_dentry in the inode */ This works usually. But problem is, inode and dentry may get released from inode and dentry cache at any time. While accessing inode/dentry I need to ensure that till the time I am accessing'em these structure remain valid in memory. Is it possible to ensure that? Which structures/locks I need to check for the purpose. Appreciate any help. Thanks! -- Joshi _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
