LTT Next Generation Roadmap

* TODO
-(1) Announce LTTng patches on LKML.
-(3) Find a way to make logging know when it causes a minor page fault -recursively (without ignoring silently all nested events).
-(3) Have various subbuffer sizes for high and low rate channels.
+(2) Post a "lite" LTTng version to LKML (core only).
+(2) Post an updated LTTng version to LKML (2.6.18-rcX).
(3) Change the byte pair "facility, event" id for a short combining the informatinon.
-(3) Add sysenter instrumentation on x86. Verify x86_64.
-(3) #IBM Fix ppc64 syscall time accounting. Maybe caused by a missing syscall -return instrumentation ?
-(3) Process and kernel stack dump for x86_64, for native and compat.
(4) Add Xen support.

(4) efficient dynamic event filtering while recording trace.

(4) instrument kernel bottom half irqsave, spinlocks, rwlocks, seqlocks, semaphores, mutexes, brlock.
-(4) In flight recorder mode, have the low traffic channels saved as normal -tracefiles and high traffic channels being flight recorder.
(4) Try to use my own non LOCK prefixed version of atomic operations : we are using per-CPU variables, so it should make it possible.
(4) integrate NPTL instrumentation (see PTT).
(4) Probe calibration kernel module.
+(4) Make page faults detect nested fault without nesting 4 times in the page +fault handler.
(5) Discuss with RelayFS upstream to integrate LTTng modifications.
