    tracepoints: add DECLARE_TRACE() and DEFINE_TRACE() · 7e066fb8
    Mathieu Desnoyers authored
    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.
