There're many tests don't remove $seqres.full before writing to it, and accumulating logs there, then the logs are always growing over time. Let's fix them once. generic/16[1-8] generic/170 and generic/33[34] truncate $seqres.full in the middle of the test, which results in partial logs. Fix them as well. xfs/227 has duplicated lines to remove $seqres.full, remove the extra line. Signed-off-by: Eryu Guan <eguan@redhat.com> Reviewed-by: Darrick J.
