From 58eacfffc41735c9155becc73cb7f4dcc60a46a9 Mon Sep 17 00:00:00 2001 From: Abderrahmane Benbachir Date: Thu, 22 Mar 2018 20:33:28 -0400 Subject: init, tracing: instrument security and console initcall trace events Trace events have been added around the initcall functions defined in init/main.c. But console and security have their own initcalls. This adds the trace events associated for those initcall functions.
