Hello: I'm trying to trace a page's behavior, from the first fresh read to any possible re-reads from swap area. I found page identity a problem. <pid, virtual add> may not identify a page due to sharing. And I find <inode, offset> would always become <swapper_inode, entry> during swapping. Are there any place to find the correspondance of these two different identities of a page. Or is there a identification of a page from the frist read untill the last free? thanks. __________________________________________________ Do You Yahoo!? Try FREE Yahoo!
