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?
