    sys/ufs/ffs          ffs_balloc.c 
  Log:
  MFC rev. 1.52:
  The ffs_balloc() routines, whan allocating the indirect blocks for
  the inode, do the rollback in case the allocation failed (due to
  insufficient free space or quota limits). But, the code does leaves the
  buffers corresponding to the inoirect blocks on the vnode bufobj list.
  This causes several assertion failures (for instance, "ffs_truncate3"
  in ffs_truncate()) to fail, and could result in the indirect block
  aliasing problem, like writing the context of such blocks to random
  disk location.
  
  Remove the buffers from the bufobj properly.
