CONFIG_SLUB_DEBUG is on by default because it compiles into the kernel the runtime configurable debugging framework. It does not activate any debugging. CONFIG_SLUB_DEBUG_ON is the equivalent to CONFIG_SLAB_DEBUG. The kernel will boot with debugging on without any extra kernel options with these. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
