I was going to ask about this - not being able to remount rw is a serious problem because many users have only the root filesystem and this limitation basically prevents this patch from being landable. I'd suggest if the filesystem is going to be remounted read/write that the journal mapping be discarded and the journal replayed. Depending on how you do the mapping it may be necessary to invalidate all of the pages in the cache so that they don't reference the blocks in the journal.
