From 077faf3dc7cc13c3bd784613304bf38696b591da Mon Sep 17 00:00:00 2001 From: "Tzvetomir Stoyanov (VMware)" Date: Thu, 19 Sep 2019 17:23:41 -0400 Subject: libtraceevent: Move traceevent plugins in its own subdirectory All traceevent plugins code is moved to tools/lib/traceevent/plugins subdirectory. It makes traceevent implementation in trace-cmd and in kernel tree consistent. There is no changes in the way libtraceevent and plugins are compiled and installed. Committer notes: Applied fixup provided by Steven, fixing the tools/perf/Makefile.perf target for the plugin dynamic list file. Problem noticed when cross building to aarch64 from a Ubuntu 19.04 container.
