Subject: [PATCH 379/379] glusterd: add missing synccond_broadcast()
14f8ab
14f8ab
After the changes in commit 3da22f8cb08b05562a4c6bd2694f2f19199cff7f,
14f8ab
there was a place where synccond_broadcast() was missing. It could
14f8ab
cause a hang if another synctask was waiting on the condition variable.
