ocfs2_replay_truncate_records
ocfs2_start_trans
down_read(&osb->journal->j_trans_barrier)
Something is wrong, so it goes out.
The ocfs2_commit_trans is not called, so up_read is not called, as to
cause the node blocked.
ocfs2_commit_trans(osb, handle)
up_read(&journal->j_trans_barrier)
So we have a patch to avoid it.

Subject: [PATCH] If there is error in the function
ocfs2_replay_truncate_records, the function
ocfs2_commit_trans should be called before return to avoid
node blocked
