However _xfs_metadump() would append the '-o' option causing the metadump to be unobfuscated. This commit fixes the bug by modifying _xfs_metadump() to no longer append any metadump options. The direct/indirect callers of this function now pass the required options explicitly. Reviewed-by: Darrick J.
