Unfortunately, at the moment this flag is not visible in ftrace output, and this makes it difficult to analyze the accounted allocations. This patch adds boolean "accounted" entry into trace output, and set it to 'true' for calls used __GFP_ACCOUNT flag and for allocations from caches marked with SLAB_ACCOUNT. Set it to 'false' if accounting is disabled in configs.
