Subject: [PATCH 379/379] glusterd: add missing synccond_broadcast()
|
|
|
e3c68b |
|
|
|
e3c68b |
After the changes in commit 3da22f8cb08b05562a4c6bd2694f2f19199cff7f,
|
|
|
e3c68b |
there was a place where synccond_broadcast() was missing. It could
|
|
|
e3c68b |
cause a hang if another synctask was waiting on the condition variable.
