| # AIO/DIO stress test |
| # Run random AIO/DIO activity on an file system with unwritten regions |
| # |
| # This test verifies that the an unwritten extent is properly marked |
| # as written after writing into it. |
| # |
| # There was a hard-to-hit bug which would occasionally trigger with |
| # ext4 for which this test was a reproducer. This has been fixed |
| # after moving ext4 to use iomap for Direct I/O's, although as of this |
| # writing, there are still some occasional failures on ext4 when block |
| # size < page size. |
