It seems pstore dump the messages with a same guid. But when loading
them, pstore check if they are exist by id in pstore_mkfile():
list_for_each_entry(pos, &allpstore, list) {
if (pos->type == type &&
pos->id == id &&
pos->psi == psi) {
rc = -EEXIST;
break;
}
}
So pstore incorrectly mark many entries as -EEXIST.
Please correct me if I am wrong. :-) And I'm preparing a patch for it.
