From 9a7df41a9e5361049a17c8aa971b52599fba2632 Mon Sep 17 00:00:00 2001 From: Lukas Larsson Date: Wed, 19 Sep 2018 16:37:55 +0200 Subject: erts: Move reason in dist messages to payload The dist messages EXIT, EXIT2 and MONITOR_DOWN have been updated with new versions that send the reason term as part of the payload of the message instead of as part of the control message. This allows the decode of the reason to be done by the receiving process instead of the dist entry which in turn makes it possible for multiple decodes to be done in parallel. This change is done in order to make it easier to fragment the potentially large payload of EXIT, EXIT2 and MONITOR_DOWN into multiple distribution messages.
