Previously, nilfs was cloning pages for mmapped region to freeze their data and ensure consistency of checksum during writeback cycles. A private page allocator was used for this page cloning. But, we no longer need to do that since clear_page_dirty_for_io function sets up pte so that vm_ops->page_mkwrite function is called right before the mmapped pages are modified and nilfs_page_mkwrite function can safely wait for the pages to be written back to disk. So, this stops making a copy of mmapped pages during writeback, and eliminates the private page allocation and deallocation functions from nilfs.
