2009-06-17kmemleak: Rename kmemleak_panic to kmemleak_stopCatalin Marinas
This is to avoid the confusion created by the "panic" word. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Acked-by: Pekka Enberg <penberg@cs.helsinki.fi>
2009-06-17kmemleak: Only use GFP_KERNEL|GFP_ATOMIC for the internal allocationsCatalin Marinas
Kmemleak allocates memory for pointer tracking and it tries to avoid using GFP_ATOMIC if the caller doesn't require it. However other gfp flags may be passed by the caller which aren't required by kmemleak. This patch filters the gfp flags so that only GFP_KERNEL | GFP_ATOMIC are used.

2009-06-11kmemleak: Add the base supportCatalin Marinas
This patch adds the base support for the kernel memory leak detector. It traces the memory allocation/freeing in a way similar to the Boehm's conservative garbage collector, the difference being that the unreferenced objects are not freed but only shown in /sys/kernel/debug/kmemleak. Enabling this feature introduces an overhead to memory allocations.
