Merge tag 'trace-v6.4-rc7-v3' of git://git./linux/kernel/git/trace/linux-trace

Pull tracing fix from Steven Rostedt:
 "Fix user event write on buffer disabled.

  The user events write currently returns the size of what was supposed
  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, and a write is
  performed on it. Writing to the buffer that is disabled is like trying
  to write to a file opened for read only, as the buffer still can be
  read, but just not written to.

  This also includes test cases for this use case"
