Subject: [for-linus][PATCH 1/5] selftests/user_events: Test struct size match cases
From: Beau Belgrave <beaub@...ux.microsoft.com>
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.
