Date: Sat, 25 May 2019 09:57:58 -0700 From: Cong Wang <xiyou.wangcong@...il.com> To: linux-kernel@...r.kernel.org Cc: Cong Wang <xiyou.wangcong@...il.com>, Steven Rostedt <rostedt@...dmis.org>, Ingo Molnar <mingo@...hat.com> Subject: [PATCH 0/4] trace: introduce trace event injection This patchset introduces trace event injection, the first 3 patches are some trivial prerequisites, the last one implements the trace event injection. Please check each patch for details. I have tested them with both valid and invalid input on different tracepoints, it works as expected.
