From: Steven Rostedt (Red Hat) Date: Wed, 14 Jan 2015 17:24:37 +0000 (-0500) Subject: tracing: Remove extra call to init_ftrace_syscalls() X-Git-Tag: firefly_0821_release~176^2~2412^2~3 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=83829b74f54186a154ae6b586c05cdb838c2ebc6;p=firefly-linux-kernel-4.4.55.git 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.
