Jeff Layton is working on fully converting ceph. This based on top of part of Matthew Wilcox's folio changes[1] Changes: ver #2: - Reorder the patches to put both non-folio afs patches to the front. - Use page_offset() rather than manual calculation[2]. - Fix folio_inode() to directly access the inode[3].
