+ help
+ A kernel build should not cause any compiler warnings, and this
+ enables the '-Werror' flag to enforce that rule by default.
+
+ However, if you have a new (or very old) compiler with odd and
+ unusual warnings, or you have some architecture with problems,
+ you may need to disable this config option in order to
+ successfully build the kernel.
+
+ If in doubt, say Y.

+ Add support for indexing of all printk formats known at compile time
+ at <debugfs>/printk/index/<module>.
+
+ This can be used as part of maintaining daemons which monitor
+ /dev/kmsg, as it permits auditing the printk formats present in a
+ kernel, allowing detection of cases where monitored printks are
+ changed or no longer present.
+
+ There is no additional runtime cost to printk with this enabled.
