+# XFS v5 supers carry an LSN in various on-disk structures to track when
+# associated metadata was last written to disk. These metadata LSNs must always
+# be behind the current LSN as dictated by the log to ensure log recovery
+# correctness after a potential crash. This test uses xfs_db to intentionally
+# put the current LSN behind metadata LSNs and verifies that the kernel and
+# xfs_repair detect the problem.
