I am really trying to keep all the feedback straight, and I didn't know what Greg was going to do with those zsmalloc patches. However, as of last night, he didn't accept the two you mentioned as being tied to zswap-only functionality. I'll bring them back into the patchset for v5 once I/we address Andrew's feedback, which might take some time. Thanks, Seth
