Ah, yes indeed. We were discussing wether it would be better to update page->index (as this patch does) or not change vma->vm_pgoff. Bill argued that the latter would be safe, it would just limit the merge capabilities of the anon vma (and the stack rarely, if ever, merges anyway). I myself an not quite sure on the effects of ->vm_pgoff of anon vmas yet. - 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/
