I guess so.
Could you please pull together a new set of changelogs sometime?
The big-picture change here is that we now use GFP_REPEAT for hugepages,
which makes the allocations work better. But I assume that you hit some
problem with that which led you to reduce the amount of effort which
GFP_REPEAT will expend for larger pages, yes?
If so, a description of that problem would be appropriate as well.
