That'd be definitely useful. We have been reviving performance tests every time we wondered if it'd affect performance in a surprising way. But we've never put that in the mainline ;) Probably test_kmalloc_nolock_and_friends*() don't even belong slub_kunit. Perhaps worth starting small with lib/test_slab.c, and slowly move/add torture/scaling tests to there? -- Cheers, Harry / Hyeonggon
