6 could be used for debugging features that need to insert extra
7 field for every page. This extension enables us to save memory
8 by not allocating this extra memory according to boottime
19 slowdown, but helps to find certain types of memory corruption.
33 pages are not saved to the suspend image.

67 equivalent to specifying the "slab_debug" parameter on boot.
85 This is intended for use in combination with KASAN, to enable KASAN to

166 bool "Enable tracepoint to track down page reference manipulation"
170 This is a feature to add tracepoint for tracking down page reference
171 manipulation. This tracking is useful to diagnose functional failure
172 due to migration failures caused by page reference mismatches. Be
173 careful when enabling this feature because it adds about 30 KB to the

252 similar to the Boehm's conservative garbage collector, the
