Subject: [PATCH v6 5/5] trace, ras: move ras_event.h under include/trace/events
From: Naoya Horiguchi <n-horiguchi@...jp.nec.com>
Most of header files for tracepoints are located to include/trace/events or
their relevant subdirectories under drivers/. One exception is
include/ras/ras_events.h, which looks inconsistent. So let's move it to the
default places for such headers.
