*	tracepoints: add DECLARE_TRACE() and DEFINE_TRACE()	Mathieu Desnoyers	2008-11-16	2	-2/+5
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Impact: API CHANGE. Must update all tracepoint users. Add DEFINE_TRACE() to tracepoints to let them declare the tracepoint structure in a single spot for all the kernel. It helps reducing memory consumption, especially when declaring a lot of tracepoints, e.g. for kmalloc tracing. API CHANGE WARNING: now, DECLARE_TRACE() must be used in headers for tracepoint declarations rather than DEFINE_TRACE(). This is the sane way to do it. The name previously used was misleading. Updates scheduler instrumentation to follow this API change. Signed-off-by: Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca> Signed-off-by: Ingo Molnar <mingo@elte.hu>
*	tracepoints: samples, fix teardown	Mathieu Desnoyers	2008-11-16	2	-0/+2
\| \| \| \| \| \| \| \| \| \| \|	Impact: fix a bug in sample tracepoints Need a tracepoint_synchronize_unregister() before the end of exit() to make sure every probe callers have exited the non preemptible section and thus are not executing the probe code anymore.
