+I just cleaned up the LTTng trace format heavily, got rid of the +heartbeat timer (by checking for overflow at the tracing site), got rid +of the "special" compact channel; it removed about 5 FIXMEs in LTTng +(cpu hotplug and compact channel related). Everything is compact now :
+
+This is much more compact than the previous format, and permits a +"tracer debug mode" in menuconfig which enables the "event size" field, +which helps cross-checking the size expected by the userspace tool and +the size written by the kernel.
+
+Note that this "event size" field can eventually be enabled on a +per-event or per-channel basis. This will probably be useful to encode +"binary blobs"...
+
+I also cleanup up the subbuffer header to make is much smaller than the +previous one by removing unneeded information.
+
+I renamed the "facilities" channel to a better name : "metadata". It +contains marker descriptions.
+
+The trace major number is bumped to "2" and is completely incompatible +with old LTTV.
