ext3_orphan_add() and ext3_orphan_del() functions lock sb->s_lock with a transaction started with ext3_mark_recovery_complete() waits for a transaction holding sb->s_lock, thus leading to a possible deadlock. At the moment we call ext3_mark_recovery_complete() from ext3_remount() we have done all the work needed for remounting and thus we are safe to drop sb->s_lock before we wait for transactions to commit. Note that at this moment we are still guarded by s_umount lock against other remounts/umounts.
