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
