I guess I've expressed myself in a poor way - sorry!
What I'm planning to do in the altera_edac notifier is:
if (kdump_is_set)
return;
/* regular code */
In other words: if the kdump is set, this notifier will be effectively a
nop (although it's gonna be called).
Lemme know your thoughts Tony, if that makes sense.
Thanks,
Guilherme
