Message-ID: <20220330155835.5e1f6669@gandalf.local.home> Date: Wed, 30 Mar 2022 15:58:35 -0400 From: Steven Rostedt <rostedt@...dmis.org> To: LKML <linux-kernel@...r.kernel.org> Cc: Beau Belgrave <beaub@...ux.microsoft.com>, Masami Hiramatsu <mhiramat@...nel.org>, linux-trace-devel <linux-trace-devel@...r.kernel.org>, bpf <bpf@...r.kernel.org>, Network Development <netdev@...r.kernel.org>, Mathieu Desnoyers <mathieu.desnoyers@...icios.com>, Alexei Starovoitov <alexei.starovoitov@...il.com>, Linus Torvalds <torvalds@...ux-foundation.org> Subject: [PATCH v2] tracing: Set user_events to BROKEN From: "Steven Rostedt (Google)" <rostedt@...dmis.org> After being merged, user_events become more visible to a wider audience that have concerns with the current API. It is too late to fix this for this release, but instead of a full revert, just mark it as BROKEN (which prevents it from being selected in make config). Then we can work finding a better API. If that fails, then it will need to be completely reverted.
