From f631718de3ca24a9ae03595e937fe0b64cfaf456 Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (VMware)" Date: Fri, 3 Mar 2017 13:43:34 -0500 Subject: [PATCH] ftrace: Move ftrace_init() to right after memory initialization Initialize the ftrace records immediately after memory initialization, as that is all that is required for the records to be created. This will allow for future work to get function tracing started earlier in the boot process.
