Re: [Lse-tech] [PATCH 1/2] node affine NUMA scheduler

[Martin J. Bligh]

I tried putting back the current->node logic now that we have
the correct node IDs, but it made things worse (not as bad as
before, but ... looks like we're still allocing off the wrong
node.

This run is the last one in the list.
