Subject: [PATCH 2/2] selftests/user_events: Test struct size match cases
Date:   Thu, 29 Jun 2023 23:50:49 +0000

The self tests for user_events currently does not ensure that the edge
case for struct types work properly with size differences.

Add cases for mis-matching struct names and sizes to ensure they work
properly.
