This patch appears to cause xfs/071 to fail:



     Writing 512 bytes, offset is +0 (direct=false)
    -pwrite64: File too large
    +non-numeric offset argument -- <OFFSET>
     Reading 512 bytes (direct=false)
     read 0/512 bytes at offset <OFFSET>
    ...
    (Run 'diff -u tests/xfs/071.out /home/dave/src/xfstests-dev/results//xfs/071.out.bad'  to see the entire diff)

Can you have a look into this?

Cheers,

Dave.
