Not that 'structleak' is all that much better, because it's not necessarily just about structs either. 'stack variable initialization' is too long. I dunno. But it's more about "variables" (and in the case of kmalloc etc - perhaps 'allocations') than "memory", I feel. The point is that in the kernel we do memory management and memory initialization, and that's something very different. Linus
