Hi,

I think HMM would be a good long term solution indeed. For now I would
want to keep ODP and HMM side by side (as the patchset seem to do)
mainly since HMM is introduced as a STAGING feature and ODP is part of
the mainline kernel.

It would be nice if you could provide a git repository to access the
patches. I couldn't apply them to the current linux-next tree.

A minor thing: I noticed some style issues in the patches. You should
run checkpatch.pl on the patches and get them to match the coding style.

Regards,
Haggai
