Would you recommend the user (me) build or install one of the newer Linux kernels? Do you have a specific version or tree that you would prefer I attempt to build or install? Please let me know. I may decide, some time today, to grab the latest stable Linux kernel and build it anyways, just for "fun," after my class today.
Running with the latest Linus' tree with the same config might tell us more. There are certainly other changes in MM that might make a difference. 2c012a4ad1a2 ("mm: vmscan: scan anonymous pages on file refaults") can definitely cause more swapping. I was not particularly happy about the patch (https://lore.kernel.org/linux-mm/20190712071359.GN29483@dhcp22.suse.cz/). Another option would be trying with that one reverted. Let me know if you need a help with that. -- You are receiving this mail because: You are the assignee for the bug.
