> Here's the latest version of swap over NFS series since -v20 last October. We decide to push
> this feature as it is useful for NAS or virt environment.
>
> The patches are against the mmotm-2010-07-01. We can split the patchset into following parts:
>
> Patch 1 - 12: provides a generic reserve framework. This framework
> could also be used to get rid of some of the __GFP_NOFAIL users.
>
> Patch 13 - 15: Provide some generic network infrastructure needed later on.
>
> Patch 16 - 21: reserve a little pool to act as a receive buffer, this allows us to
> inspect packets before tossing them.
>
> Patch 22 - 23: Generic vm infrastructure to handle swapping to a filesystem instead of a block
> device.
>
> Patch 24 - 27: convert NFS to make use of the new network and vm infrastructure to
> provide swap over NFS.
>
> Patch 28 - 30: minor bug fixing with latest -mmotm.
