protocol: Add framework to send transaction id with recall
Issue: The upcall(cache invalidation/recall) event is sent from the bricks to clients. In AFR/EC setup, it can so happen that all the bricks will send the upcall for the same event, and if AFR/EC doesn't filter out these duplicate notifications, the logic above cluster xlators can fail. Solution: Use transaction id to filter out duplicate notifications. This patch adds framework for duplicate notifications. AFR/EC can build up on this patch for deduping the notifications Change-Id: I66b08e63b8799bc5932f2b2545376138a5701168 BUG: 1319992 Signed-off-by: Poornima G <pgurusid@redhat.com> Reviewed-on: http://review.gluster.org/14647 Smoke: Gluster Build System <jenkins@build.gluster.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Raghavendra Talur <rtalur@redhat.com> Reviewed-by: Raghavendra G <rgowdapp@redhat.com>
