* tracepoints: documentation fix for teardownMathieu Desnoyers2008-11-161-4/+6
| | | | | | | | | | | Impact: documentation update 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.

* tracepoints: add DECLARE_TRACE() and DEFINE_TRACE()Mathieu Desnoyers2008-11-161-1/+6
| | | | | | | | | | | | | | | | | | 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.
