RE: [PATCH v4] ACPI: APEI: fix missing erst record id

[Luck, Tony]

I think it might be a cleaner solution if you first implement a new function:

/*
 * Like erst_read(), but look for a specific record type (by size and guid)
 * also retry -ENOENT returns by skipping to next record_id
 */
ssize_t erst_read_record(u64 *record_id, struct cper_record_header *record,
			size_t buflen, size_t recordlen, const guid_t *guid)
{
}

Step 2: Update apei_read_mce() and erst_reader() to use this function.

Step 3: Apply your erst_clear_cache() fix to the new function
