| # FS QA Test No. 628 |
| # |
| # Make sure that reflink forces the log out if we open the file with O_SYNC or |
| # set FS_XFLAG_SYNC on the file. We test that it actually forced the log by |
| # using dm-error to shut down the fs without flushing the log and then |
| # remounting to check file contents. This is a regression test for commit |
| # 5ffce3cc22a0 ("xfs: force the log after remapping a synchronous-writes file") |
