Don't be misled.  Swapping over NFS is just a scarecrow for the
seemingly real impetus behind these changes which is network storage
stuff like iSCSI.

So can we please do swap over network storage only first?  All these
VM bits look conceptually sane to me, while the changes to the swap
code to support nfs are real crackpipe material.

Yeah, I know how you stand on that. I just wanted to post all this
before going off into the woods reworking it all.

So please get the VM bits for swap over network blockdevices in first,

Trouble with that part is that we don't have any sane network block
devices atm, NBD is utter crap, and iSCSI is too complex to be called
sane.

Maybe Evgeniy's Distributed storage thingy would work, will have a look
at that.

Andrew recently asked Evgeniy if his DST was ready for merging; to
which Evgeniy basically said yes:
http://lkml.org/lkml/2007/10/27/54

It would be great if DST could be merged; whereby addressing the fact
that NBD is lacking for net-vm.  If DST were scrutinized in the
context of net-vm it should help it get the review that is needed for
merging.
