Now function ocfs2_replay_truncate_records() first modifies tl_used, then calls ocfs2_extend_trans() to extend transactions for gd and alloc inode used for freeing clusters. jbd2_journal_restart() may be called and it may happen that tl_used in truncate log is decreased but the clusters are not freed, which means these clusters are lost. So we should avoid extending transactions in these two operations.
