My own guess is that it is due to a different persistence of various caches. I haven't seen anyone before blaming stack frame allocation as a /cause/ of fragmenation - I've heard people say they notice fragmentation more as stack frame allocs start to fail - but that's a symptom. -- Alex Bligh - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||
