Currently pstore has function trace support which can be
used to get the function call chain with limited data.
Event tracing has extra data which is useful to debug wide
variety of issues and is heavily used across the kernel.

Adding this support to pstore can be very helpful to debug
different subsystems since almost all of them have trace
events already available. And also it is useful to debug
unknown resets or crashes since we can get lot more info
from event tracing by viewing the last occurred events.

Anyone here?

Sorry for the top post. I've been wanting to do this as well for some time.
It's quite useful. I am out of office this week and away from work machine.
I will take a look at your patches next week once I'm back at work. Thanks.

If Steven agrees this shouldn't live in ftrace directly and Joel
reviews these patches, I think it should be fine. I'm travelling, but
I can review it hopefully later this week.

Thank you Kees.
