		# Shipment builds (user variants) should not have any debug feature

		# are identified using the CONFIG_SLUB_DEBUG_ON configuration. Since

		# representation of perf builds (identified using the string 'perf'),
		# is used to identify if the build is a slub or defconfig one. This
		# way no critical debug feature will be enabled for perf and shipment
		# builds. Other OEMs are also protected using the TARGET_BUILD_VARIANT
