In ext2fs we are only avoiding double caching: it is assumed that the application (usually databases) knows why it's setting O_DIRECTIO and do their own caching. From what I discussed with Tor Egge it is useful. cheers, Pedro. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "[email protected]"
