[for-next][PATCH 1/3] ftrace: Decrement count for dyn_ftrace_total_info for init functions

Show all headers | View raw

From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

Init boot up functions may be traced, but they are also freed when the
kernel finishes booting. These are removed from the ftrace tables, and the
debug variable for dyn_ftrace_total_info needs to reflect that as well.
