Forget that one - OpenAFS cannot be used for swapping.

And it seems the reason for patching kernels is exactly that: usage of
Network Block Devices (NBDs) for swapping. The original NBD _is_
distributed with the mainline kernel, but seems to not reliably dela
with swapping...

Someone knowledgeable in this field please correct me or add good
references here (the seemingly official place for the NBD swap patch is
suspiciously old: http://www.xss.co.at/linux/NBD/Applications.html).
