Hello, I'm doing some work in page cache handling and I have noticed that NFS is the only user of mapping->a_ops->freepage callback. From a quick look I don't see why isn't NFS using ->releasepage / ->invalidatepage callback as all other filesystems do? I agree you would have to set PagePrivate bit for those to get called for the directory mapping however that would seem like a cleaner thing to do anyway - in fact you do have private data in the page. Just they are not pointed to by page->private but instead are stored as page data... Am I missing something?
