[PATCH] tracer: hwlat: allow to be default bootup tracer
From: Pratyush Anand
Date: Fri Aug 11 2017 - 07:32:00 EST
hwlat is not a production kernel tracer, however it can be used to
identify any HW latency issue during kernel boot as well.Therefore call
init_hwlat_tracer() though core_initcall() so that we can pass
ftrace=hwlat in kernel commandline parameter and we can have hwlat as
default bootup tracer.
