Yes, the format has changed since this document has been updated. The
best information source would be
http://git.kernel.org/?p=linux/kernel/git/compudj/linux-2.6-lttng.git;a=blob;f=include/linux/ltt-tracer.h;h=2ae278cd4afd8d97e363e8d0a21449a20012575e;hb=HEAD
struct ltt_subbuffer_header (is also the trace header, repeated at each
subbuffer)
ltt_write_event_header() : writes the event header.
