When looking at code, it seems llog already deal with proper locking when several thread access the same llog. The codes that use this king of log do not seem to add more locking when using it. Is this correct? llog_* call can be called without taking care of concurrency? Thanks Aur?lien ^ permalink raw reply [flat|nested] 2+ messages in thread
