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
