From d5cff635290aec9ad7e6ee546aa4fae895361cbb Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Thu, 11 Jun 2009 13:22:40 +0100 Subject: kmemleak: Add the slab memory allocation/freeing hooks This patch adds the callbacks to kmemleak_(alloc|free) functions from the slab allocator. The patch also adds the SLAB_NOLEAKTRACE flag to avoid recursive calls to kmemleak when it allocates its own data structures.
