The issue also cropped up in the bug trackers of libguestfs [1]\nand the Red Hat bugzilla [2].\n\nThe problem is that when memcg is disabled with the boot time flag, the\nzswap shrinker might get called with sc->memcg == NULL. This is okay in\nmany places, like the lruvec operations. But it crashes in\nmemcg_page_state() - which is only used due to the non-node accounting of\ncgroup's the zswap memory to begin with.\n\nNhat spotted that the memcg can be NULL in the memcg-disabled case, and I\nwas then able to reproduce the crash locally as well.\n\n[1] https://github.com/libguestfs/libguestfs/issues/139\n[2] https://bugzilla.redhat.com/show_bug.cgi?id=2275252\n\ud83d\udccf Published: 2024-05-17T14:47:25.503Z\n\ud83d\udccf Modified: 2025-05-04T09:06:43.875Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/b0fdabc908a7f81d12382c87ca9e46a9c2e14042\n2. https://git.kernel.org/stable/c/682886ec69d22363819a83ddddd5d66cb5c791e1", "creation_timestamp": "2025-05-04T09:18:09.000000Z"} 2025-05-04T09:18:09+00:00
