  Compilation warning on Utopic

Bug description:
  [Impact]

  When compiling the Utopic kernel, the following warning can is shown:

  /tmp/kernel-henrix-EluZkimP/build/fs/exec.c: In function 'do_open_exec':
  /tmp/kernel-henrix-EluZkimP/build/fs/exec.c:780:18: warning: passing argument 1 of 'trace_open_exec' from incompatible pointer type
    trace_open_exec(name);
                    ^
  In file included from /tmp/kernel-henrix-EluZkimP/build/include/trace/syscall.h:4:0,

                   from /tmp/kernel-henrix-EluZkimP/build/fs/exec.c:48:

  /tmp/kernel-henrix-EluZkimP/build/include/trace/events/fs.h:32:1: note: in expansion of macro 'TRACE_EVENT'
   TRACE_EVENT(open_exec,
   ^

  This is due to a wrong parameter type being used while invoking
  trace_open_exec()

  [Test Case]

  A simple compilation of the kernel shows this warning.

  [Fix]

  A patch with the following should fix it:

  -       trace_open_exec(name);
  +       trace_open_exec(name->name);
