Subject: [for-linus][PATCH 0/3] tracing: Final updates for 6.4

Before user events become an ABI, fix the return value of the write
operation when tracing is disabled. It should not return an error, but
simply report it wrote zero bytes. Just like any other write operation
that doesn't write but does not "fail".

This also includes test cases for this use case.
