From: "Steven Rostedt (Google)" <rostedt@xxxxxxxxxxx> While working on some utilities to create synthetic events, I was testing on both older (4.19) and newer kernels and found a few bugs along the way. This fixes a memory initialization issue, and errors in displaying commands to create synthetic events that work on both new and older kernels.
