  Modified files:
    sys/ufs/ufs          ufs_extattr.c 
  Log:
  Don't allow VOP_GETEXTATTR to set uio->uio_offset != 0, as we don't
  provide locking over extended attribute operations, requiring that
  individual operations be atomic.  Allowing non-zero starting offsets
  permits applications/etc to put themselves at risk for inconsistent
  behavior.  As VOP_SETEXTATTR already prohibited non-zero write offsets,
  this makes sense.
