It's a bit diffcult. Most filesystems (at least ext3, xfs and jfs) don't use the inode's address space for directories but the address_space of the underlying block device (or in the xfs case an xfs-private one covering the whole block device), so that readahead would have to happen on the block device node after finding out where the directory is placed. ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf _______________________________________________ Jfs-discussion mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/jfs-discussion
