| |
The reference counting issue happens in two exception handling paths of ocfs2_replay_truncate_records(). When executing these two exception handling paths, the function forgets to decrease the refcount of handle increased by ocfs2_start_trans(), causing a refcount leak.
Fix this issue by using ocfs2_commit_trans() to decrease the refcount of handle in two handling paths.
