Hi Andrew,

Please drop these patches again from mmotm.

There has been a number of odd conflicts resulting in at least one major
bug where a node-counter is used on a zone that will result in random
behaviour. Some of the additional feedback is non-trivial and all of it
will need to be resolved against the OOM detection rework and the huge
tmpfs implementation.

It'll take time to resolve this and I don't want to leave mmotm in a
broken state in the meantime. I have a copy of mmots so I have the conflict
resolutions you already applied.

Thanks.
