Subject: [PATCH 38/39] STAP: Only print transaction statistics if the script
caught some transactions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If the script measured an 'id' run from the cache, there would be no
transactions and dereferencing the aggrefate would throw an error.
Reviewed-by: Fabiano Fidêncio <fidencio@redhat.com>
