From: Arnd Bergmann <arnd@arndb.de>
The CONFIG_DEBUG_LIST option is normally meant for kernel developers rather than production machines and is guarded by CONFIG_DEBUG_KERNEL.
In contrast, the newly added CONFIG_BUG_ON_DATA_CORRUPTION is meant for security hardening and may be used on systems that intentionally do not enable CONFIG_DEBUG_KERNEL. In this configuration, we get a warning from Kconfig about the mismatched dependencies:
warning: (BUG_ON_DATA_CORRUPTION) selects DEBUG_LIST which has unmet direct dependencies (DEBUG_KERNEL)
This annotates the DEBUG_LIST option to be selectable by BUG_ON_DATA_CORRUPTION when DEBUG_KERNEL is disabled.
