LTT Next Generation Roadmap
* TODO
-(1) port LTTng to 2.6.14 kernel.

-(1) Use 2.6.14 RelayFS control files.
(2) add efficient and secure user space tracing. (1 month)

(3) integrate LTTng State Dump : missing irq and process state.
# Jean-Hugues Deschenes
(4) efficient dynamic event filtering while recording trace.

+(4) Create the heartbeat timer LTTng module. Make sure that heartbeat events
+never hit the facility channel. Use the complete 64 bits TSC for the facility
+channel in every case. That's because this channel must never be overwritten
+even in "flight recorder" mode.
(5) Integrate LTTng and lttd with LKCD.
+(6) Add Xen support.
(7) add gcc -finstrument-functions instrumentation
-(3) port LTTng to : (depends on 2.6.14 port)
+(7) Integrate periodical dump of perfctr hardware counters.
+(8) Integrate periodical dump of SystemTAP computed information.
