Less coverage. Defaulting to y if CONFIG_DEBUG_VM might help, but if people do `make oldconfig' when CONFIG_DEBUG_VM=n, their CONFIG_DEBUG_VM_POISON will get set to `n' and will remain that way when they set CONFIG_DEBUG_VM again. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
