And since this is to see what other kernel configs to enable or disable to help debug fstests better on kdevops too, kasan seems to win, and I suspect I can't be the only other user who might end up concluding the same. This is easily redproducible by just *boot* on kdevops if you enable KASAN and memprofiling today. generic/531 was just another example. So hopefully kasan folks have enough info for folks interested to help chase it down. Luis
