If one of the tools reports a problem when the other passed the filesystem, there is a problem with one of the tools

http://oss.sgi.com/bugzilla/show_bug.cgi?id=723

xfs_check finds some errors on the filesystem:

link count mismatch for inode 387655 (name ?), nlink 0, counted 2
link count mismatch for inode 13313696 (name ?), nlink 0, counted 2
link count mismatch for inode 17197100 (name ?), nlink 0, counted 2

xfs_repair reports no problems:
