Subject: [PATCH 399/449] glusterd: coverity fixes
|
|
|
14f8ab |
|
|
|
14f8ab |
1400775 - USE_AFTER_FREE
|
|
|
14f8ab |
1400742 - Missing Unlock
|
|
|
14f8ab |
1400736 - CHECKED_RETURN
|
|
|
14f8ab |
1398470 - Missing Unlock
|
|
|
14f8ab |
|
|
|
14f8ab |
Missing unlock is the tricky one, we have had annotation added, but
|
|
|
14f8ab |
coverity still continued to complaint. Added pthread_mutex_unlock to
|
|
|
14f8ab |
clean up the lock before destroying it to see if it makes coverity
|
|
|
14f8ab |
happy.
