| # Open a file several times, write to it, fsync on all fds and make sure that |
| # they all return 0. Change the device to start throwing errors. Write again |
| # on all fds and fsync on all fds. Ensure that we get errors on all of them. |
| # Then fsync on all one last time and verify that all return 0. |
