The recent busted fsx updates caused fsx to execute fsx with direct IO and mmapped reads and writes on an XFS filesystem. The result uncovered a direct-IO write vs mmap read bug to do with EOF sub-block zeroing on the direct IO write. Hence whiel we do not recommend that pepole mix DIO with mmap on the same file, we should at least have tests that exercise it as they often show up other problems like this.
