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-Tag: v2.12.9~6 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=ad5e2bb2bca506a7640c90cf0a4d40873ef618bf;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___".
