Subject: [PATCH 204/212] glusterd : memory leak in mgmt_v3 lock functionality

|
|
|
a3470f |
In order to take care of stale lock issue, a timer was intrduced
|
|
|
a3470f |
in mgmt_v3 lock. This timer is not freeing the memory due to
|
|
|
a3470f |
which this leak got introduced
|
|
|
a3470f |
|
|
|
a3470f |
With this fix now memory cleanup in locking is handled properly
