Subject: [PATCH v3 18/19] refs.c: free the transaction before returning when number of updates is 0
Date: Fri, 25 Apr 2014 09:14:53 -0700	[thread overview]
Message-ID: <1398442494-23438-19-git-send-email-sahlberg@google.com> (raw)
In-Reply-To: <1398442494-23438-1-git-send-email-sahlberg@google.com>

We have to free the transaction before returning in the early check for
'return early if number of updates == 0' or else the following code would
create a memory leak with the transaction never being freed :
   t = ref_transaction_begin()
   ref_transaction_commit(t)
