[PATCH 2/3] kbuffer: Add event if the buffer just fits in kbuffer_read_buffer()

[Steven Rostedt <rostedt@goodmis.org>]

From: "Steven Rostedt (Google)" <rostedt@goodmis.org>

If the buffer passed in is exactly the size needed to add an event, it will
not because it checks with:

  while (len > kbuf->next - save_curr) {

Instead of

  while (len >= kbuf->next - save_curr) {
