I did (assuming you're referring to the shared page table discussion; see http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&oe=UTF-8&threadm=E1844h3-0002Bt-00%40w-gerrit2&rnum=4&prev=/groups%3Fq%3Dben%2Blahaise%26hl%3Den%26lr%3D%26ie%3DUTF-8%26oe%3DUTF-8%26scoring%3Dd%26selm%3DE1844h3-0002Bt-00%2540w-gerrit2%26rnum%3D4). There is nothing new there. Now if you'd read the original discussion, you'd see that Linus considered those objections and still preferred separate system calls. You have to realize that the huge page syscalls are NOT a replacement for transparent superpages. They serve a different purpose and have a different scope (we're talking about pages of the size of 256MB and more, not merely something that's a small multiple of the base page size). Please apply the patch. --david
