Subject: [PATCH v6 09/42] refs.c: change ref_transaction_create to do error checking and return status
Date: Thu, 1 May 2014 13:37:09 -0700 [thread overview]
Message-ID: <1398976662-6962-10-git-send-email-sahlberg@google.com> (raw)
In-Reply-To: <1398976662-6962-1-git-send-email-sahlberg@google.com>
Do basic error checking in ref_transaction_create() and make it return
status. Update all callers to check the result of ref_transaction_create()
There are currently no conditions in _create that will return error but there
will be in the future.
