If you are going to answer with a Google search, at least have the
courtesy of cleaning up the url. We don't need all those parameters.
Something short like this suffices:

http://www.google.com/#q=swap+file+btrfs

Meanwhile Google is already poisoned and this search is biting its own
tail. The top results are topics from this thread, which makes a Google
search useless.

That being said, I believe that this is the answer to the question:
