AFAIK it doesn't, it expects a continuous file without fragmentation.
On btrfs systems, for example, I have to set a bit to disable COW for the file to be used as a swapfile, otherwise it will not work.

I also found mention about the bypass mechanism. http://lkml.iu.edu/hypermail/linux/kernel/0507.0/1690.html http://lkml.iu.edu/hypermail/linux/kernel/0507.0/1690.html
