Well, MCE_PRIO_EARLY will emit a trace record so that if you have error events
consumers like rasdaemon, it'll get that error record for reporting etc.
MCE_PRIO_UC calls memory_failure() on the error and thus offlines the page.
Functionality which you're partly replicating in your notifier.
And since you wanna do the same thing, why are you even adding a new priority
instead of using MCE_PRIO_UC? amdgpu_bad_page_notifier() uses that same prio
because it does a similar thing.
