From: "Steven Rostedt (Google)" <rostedt@xxxxxxxxxxx>
If the tep handle that returns the kbuf from tep_kbuffer() did not have its
long_size initialized, neither will the kbuffer it returns. This can cause
inconsistent results. Default the long_size to the "commit" size of the header
page as that should also be the size of long.
Fixes: 21ba6336 ("libtraceevent: Add kbuffer_create()")
