Let's simplify it a little - I've dropped RAS_TRACE for now. We can carve it out later, when needed. --- From: "Chen, Gong" <gong.chen@xxxxxxxxxxxxxxx> Subject: [PATCH 1/7 v5] trace, RAS: Add basic RAS trace event To avoid confuision and conflict of usage for RAS related trace event, add an unified RAS trace event stub. Start a RAS subsystem menu which will be fleshed out in time, when more features get added to it.
