With the new checks in xfs_repair, it outputs more information about errors found than previously. This new output can be ignored for the purposeѕ of this test, so filter it all out. This will allow the test to run on new and old reapir binaries. Signed-off-by: Dave Chinner <david@fromorbit.com> Reviewed-by: Christoph Hellwig <hch@lst.de>
