+config KASAN
+	bool "KASan: runtime memory debugger"
+	help
+	  Enables kernel address sanitizer - runtime memory debugger,
+	  designed to find out-of-bounds accesses and use-after-free bugs.
+	  This is strictly debugging feature. It consumes about 1/8
+	  of available memory and brings about ~x3 performance slowdown.
+	  For better error detection enable CONFIG_STACKTRACE,
+	  and add slub_debug=U to boot cmdline.

+config KASAN_OUTLINE
+	bool "Outline instrumentation"
+	help
+	  Before every memory access compiler insert function call
+	  __asan_load*/__asan_store*. These functions performs check
+	  of shadow memory. This is slower than inline instrumentation,
+	  however it doesn't bloat size of kernel's .text section so
+	  much as inline does.
+
+config KASAN_INLINE
+	bool "Inline instrumentation"
+	help
+	  Compiler directly inserts code checking shadow memory before
+	  memory accesses. This is faster than outline (in some workloads
+	  it gives about x2 boost over outline instrumentation), but
+	  make kernel's .text size much bigger.
