Date: Thu, 10 Jul 2008 21:06:06 +0300 From: Eduard - Gabriel Munteanu <eduard.munteanu@...ux360.ro> To: penberg@...helsinki.fi Cc: linux-kernel@...r.kernel.org, linux-mm@...ck.org Subject: [RFC PATCH 2/5] Add new GFP flag __GFP_NOTRACE. __GFP_NOTRACE turns off allocator tracing for that particular allocation. This is used by kmemtrace to correctly classify different kinds of allocations, without recording one event multiple times. Example: SLAB's kmalloc() calls kmem_cache_alloc(), but we want to record this only as a kmalloc.
