But the bisection result is not correct. This bug is actually much older. Note that commit 80a9201a596 changes Kconfig dependency - it removes depends on SLUB_DEBUG from config KASAN section. And yours config has: # CONFIG_SLUB_DEBUG is not set So you simply test c146a2b98e with CONFIG_KASAN=n and 80a9201a59 with CONFIG_KASAN=y -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
