It would be interesting to hear as much as possible about this: if Manfred's bio patch makes a difference, it's less intrusive than mine, and as such interesting. On the other hand, despite the small size of Manfred's patch, it does have a big impact: since 128 bytes is a "watermark" for the slab debugging, the patch which appears less intrusive does in fact still cause a big amount of changes. Anyway, the more you feel like testing, the better. But use your own judgements. Thanks a lot for the effort, btw, Linus
