Wong The goal of this test is to ensure that log recovery finishes a copy on write operation in the event of temporary media errors. It's important that the test observe some sort of IO error once we switch the scratch device to fail all IOs, but regrettably the test encoded the specific behavior of XFS and btrfs when the test was written -- the aio write to the page cache doesn't have to touch the disk and succeeds, and the fdatasync flushes things to disk and hits the IO error. However, this is not how things work on the XFS realtime device. There is no delalloc on realtime, so the aio write allocates an unwritten extent to stage the write. The allocation fails due to EIO, so it's the write call that fails. Therefore, all we need to do is to detect an IO error at any point between the write and the fdatasync call to be satisfied that the test does what we want to do. Signed-off-by: Darrick J.
