My view of the notification is:
1) Oops happens, gets written to persistent store.
2) fs/pstore code makes a file appear in /dev/pstore
3) Daemon that's watching /dev/pstore sees new file
4) File is read, copied some place safe and fsync'd
5) Daemon unlinks file from /dev/pstore
6) fs/pstore code tells platform level to erase record
