I haven't dont a -o delalloc test in a while, but at one point, probably about 2-3 months ago, I did do a regression test run using the xfsqa test suite with -o delalloc. Of course, just because mainline -o delalloc has been tested doesn't say that much about RHEL 5.4's -o delalloc --- there's a reason why it was labelled a Technology Preview on RHEL 5.4. :-) - Ted
