From 83829b74f54186a154ae6b586c05cdb838c2ebc6 Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Red Hat)" Date: Wed, 14 Jan 2015 12:24:37 -0500 Subject: [PATCH] tracing: Remove extra call to init_ftrace_syscalls() trace_init() calls init_ftrace_syscalls() and then calls trace_event_init() which also calls init_ftrace_syscalls(). It makes more sense to only call it from trace_event_init(). Calling it twice wastes memory, as it allocates the syscall events twice, and loses the first copy of it.
