+# Test XFS log recovery ordering on v5 superblock filesystems. XFS had a problem
+# where it would incorrectly replay older modifications from the log over more
+# recent versions of metadata due to failure to update metadata LSNs during log
+# recovery. This could result in false positive reports of corruption during log
+# recovery and permanent mount failure.
+#
+# To test this situation, run frequent shutdowns immediately after log recovery.
+# Ensure that log recovery does not recover stale modifications and cause
+# spurious corruption reports and/or mount failures.
