Subject: [PATCH 0/4] trace: introduce trace event injection
Date: Sat, 25 May 2019 09:57:58 -0700	[thread overview]
Message-ID: <20190525165802.25944-1-xiyou.wangcong@gmail.com> (raw)

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.
