RAS user space tools like rasdaemon which base on trace event, could
receive mce error event, but no memory recovery result event. So, I
want to add this event to make this scenario complete.
This patchset add a event at ras group for memory-failure.
The output like below:
# tracer: nop
#
# entries-in-buffer/entries-written: 2/2 #P:24
#
# _-----=> irqs-off
# / _----=> need-resched
# | / _---=> hardirq/softirq
# || / _--=> preempt-depth
# ||| / delay
# TASK-PID CPU# |||| TIMESTAMP FUNCTION
# | | | |||| | |

v5->v6:
- fix a build error
- move ras_event.h under include/trace/events
- rebase on top of latest mainline
v4->v5:
- fix a typo
- rebase on top of latest mainline
v3->v4:
- rebase on top of latest linux-next
- update comments as Naoya's suggestion
- add #ifdef CONFIG_MEMORY_FAILURE for this trace event
- change type of action_result's param 3 to enum
v2->v3:
- rebase on top of linux-next
- based on Steven Rostedt's "tracing: Add TRACE_DEFINE_ENUM() macro
to map enums to their values" patch set v1.
v1->v2:
- Comment update
- Just passing 'result' instead of 'action_name[result]',
suggested by Steve. And hard coded there because trace-cmd
and perf do not have a way to process enums.
