Still fails on -rc7+ [1]. Even with `xfs_repair $SCRATCH_DEV` before mount, it still fails [2].
But `xfs_repair -L` helps, the test can keep running after that.
Do you think it's a xfs issue, or a case issue (xfs need a log cleanup at here?).
Thanks,

ERROR: The filesystem has valuable metadata changes in a log which needs to
be replayed. Mount the filesystem to replay the log, and unmount it before
re-running xfs_repair. If you are unable to mount the filesystem, then use
the -L option to destroy the log and attempt a repair.
Note that destroying the log may cause corruption -- please attempt a mount
of the filesystem before doing this.
