But the reason for a separate hest_ia32_init() is: For now(ACPI 6.1), we have three IA-32 Architecture-specific error source structures, maybe we will parse them later. So I made this hest_ia32_init() for all these structures. maybe we can do : --- static int __init hest_parse_cmc(struct acpi_hest_header *hest_hdr, void *data) { if (hest_hdr->type != ACPI_HEST_TYPE_IA32_CORRECTED_CHECK) return 0; if (!acpi_disable_cmcff) return !arch_apei_enable_cmcff(hest_hdr, data); return 0; } static int __init hest_parse_mce(struct acpi_hest_header *hest_hdr, void *data) { if (hest_hdr->type != ACPI_HEST_TYPE_IA32_CHECK) return 0; // do something return 0; } static int __init hest_parse_nmi(struct acpi_hest_header *hest_hdr, void *data) { if (hest_hdr->type != ACPI_HEST_TYPE_IA32_NMI) return 0; // do something return 0; } static inline int __init hest_ia32_init(void) { int ret = apei_hest_parse(hest_parse_nmi, NULL); if (ret) return ret; ret = apei_hest_parse(hest_parse_mce, NULL); if (ret) return ret; return apei_hest_parse(hest_parse_cmc, NULL); } --- But it is just my thought, please correct me if I misunderstand something.
