349 | Say Y here if you want to enable the memory leak | ||
350 | detector. The memory allocation/freeing is traced in a way | ||
351 | similar to the Boehm's conservative garbage collector, the | ||
352 | difference being that the orphan objects are not freed but | ||
353 | only shown in /sys/kernel/debug/kmemleak. Enabling this | ||
354 | feature will introduce an overhead to memory | ||
355 | allocations. See Documentation/kmemleak.txt for more | ||
356 | details. | ||
