It already has been done for direct IO by Eric as per commit a1e09b03e6f5 ("f2fs: use iomap for direct I/O"), not clear to me if anyone is working on buffered-io. Then f2fs_commit_super() seems to be the last buffer-head user, and its not clear what the replacement could be yet. Jaegeuk, Eric, have you guys considered this?
