d by the use of "offs", since we tend to use the notion of
  "offset" not as an absolute position, but as an offset _within_ a page
  or allocation.

  Alternatively, a "pgoff_t" is a page index, but not a byte offset -
  our VM naming can be a bit confusing.

  So in this case, a VM person would likely have called this a "pos",
  not an "offs", or perhaps talked about byte offsets rather than page
  offsets (since it's counted in bytes, not pages).    - Linus ]
