From: Mathieu Desnoyers Date: Mon, 4 Apr 2022 19:49:32 +0000 (-0400) Subject: Fix: tracepoint event: allow same provider and event name X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=a7eb2e3d0a4beb1ee80b132927641dd05ef2d542;p=lttng-modules.git Fix: tracepoint event: allow same provider and event name Using the same name for the provider (TRACE_SYSTEM) and event name causes a compilation error because the same identifiers are emitted twice. Fix this by prefixing the provider identifier with "__provider_event_desc___".
