You are expected to not use function names at all, in order to provide a title readable by someone who does not know the function or structure names of this area. In this case, it can be: event: fix ring init failure handling > - Added memzone free (good catch, thanks Jerin) > - Return NULL instead of 0 (Jerin) > - Added Jerin's Ack > > Cc: thomas@monjalon.net > Cc: jerin.jacob@caviumnetworks.com > > Please consider this for RC3, as it fixes the unit tests > on 32-bit systems. Applied, thanks
