I think "all references" is a bit misleading since there still are several places in the kernel code that use it: $ git grep CONFIG_SRCU drivers/base/core.c:#ifdef CONFIG_SRCU drivers/base/core.c:#else /* !CONFIG_SRCU */ drivers/base/core.c:#endif /* !CONFIG_SRCU */ fs/locks.c:#if IS_ENABLED(CONFIG_SRCU) fs/locks.c:#else /* !IS_ENABLED(CONFIG_SRCU) */ fs/locks.c:#endif /* IS_ENABLED(CONFIG_SRCU) */ kernel/notifier.c:#ifdef CONFIG_SRCU kernel/notifier.c:#endif /* CONFIG_SRCU */ Should those be removed before this patch?
