Could somebody please document WTF writepage() is supposed to do, and WTF page_mkwrite() is for? I thought that page_mkwrite() was supposed to finally allow us to deal with dirty pages in a clean manner: the caller gets to tell the filesystem that it wants the entire page written out, and then dirties the page. What is the point if the VM then expects to be able to circumvent this?
