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

The user events write currently returns the size of what was suppose to be
written when tracing is disabled and nothing was written. Instead, behave like
trace_marker and return -EBADF, as that is what is returned if a file is opened
for read only,

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.
