Subject: [PATCH v2] trace, ras: move ras_event.h under include/trace/events
Here is the revised one.
---
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.
Signed-off-by: Naoya Horiguchi <n-horiguchi@...jp.nec.com>
---
ChangeLog v1->v2:
- rename the header from ras_event.h to ras.h (then no need to define
TRACE_INCLUDE_FILE)
- remove "#define TRACE_INCLUDE_PATH ../../include/ras" from a/drivers/ras/ras.c
