I guess this is exactly the kind of problem linux-next is designed to wring out! Greg, FOR NOW, PLEASE JUST REVERT the ramster patchset from staging-next. I am working on a v5 anyway and will roll in a copy of the xvmalloc.[ch] code into it for now and, since Seth's patch should be in linux-next by the time I am done (hopefully next week), I can test build ramster v5 with linux-next to ensure all the above problems are resolved before resubmitting. (Seth, I could also switch ramster v5 to depend on zsmalloc instead of xvmalloc, but since I've done all my ramster testing on xvmalloc, I think I would prefer to make that transition later.) Sorry, Stephen and Greg, for the hassle!
