From: Joe Stringer <joestringer@xxxxxxxxxx> 3.4.111-rc1 review patch. If anyone has any objections, please let me know. ------------------ commit 4b31814d20cbe5cd4ccf18089751e77a04afe4f2 upstream. When zones were originally introduced, the expectation functions were all extended to perform lookup using the zone. However, insertion was not modified to check the zone. This means that two expectations which are intended to apply for different connections that have the same tuple but exist in different zones cannot both be tracked.
