Is CONFIG_TWIST_KERNEL_BEHAVIOR or CONFIG_TWEAK_KERNEL_BEHAVIOR
better-named than CONFIG_KERNEL_BUILT_FOR_FUZZ_TESTING, for there
might be small modifications which would be beneficial to things
other than fuzz testing (e.g. adding some more information when
dumping backtrace, reporting locks held by TASK_RUNNING threads) ?
