Subject: LTTng 0.55 for 2.6.27.6, tracepoint updates

Hi,

LTTng 0.55 now requires tracepoints to be declared (in
include/trace/*.h), defined (in a C file), and optionally exported. The
documentation in Documentation/tracepoint.txt is updated accordingly, as
well as the LTTng instrumentation.

This removes the static declaration per-tracepoint which will make them
suitable for kmemtrace.

The main patch implementing this API change is :

http://git.kernel.org/?p=linux/kernel/git/compudj/linux-2.6-lttng.git;a=commitdiff;h=e15badc57e49250c6a8209b31014706dbb9f0212;hp=8233bb29925bd807619d800d28aaf694221f72ab

I will post updates to tracepoints and markers ported to 2.6.28-rc soon.

Mathieu
