  OK, I've updated the test as you suggested. Result is attached.

Subject: [PATCH v4] Make test 272 work for ext3

ext3 does not support direct IO for files with data journalling. This
confuses test 272. Make the test check whether open succeeds and perform
the writing only if it does.

Thanks for Dave Chinner for suggesting a simpler way to fix the test.
