This patch improves the migration of dirty pages and allows migrating atomic written pages that F2FS uses in Page Cache. Instead of the fallback releasing page path, it provides better performance for memory compaction, CMA and other users of memory page migrating. For dirty pages, there is no need to write back first when migrating. For an atomic written page before committing, we can migrate the page and update the related 'inmem_pages' list at the same time.
