Date: Fri, 19 Dec 2008 18:13:35 +0000 From: Catalin Marinas <catalin.marinas@....com> To: linux-kernel@...r.kernel.org Subject: [PATCH 07/14] kmemleak: Add kmemleak_alloc callback from alloc_large_system_hash The alloc_large_system_hash function is called from various places in the kernel and it contains pointers to other allocated structures. It therefore needs to be traced by kmemleak.
