From 36b0256e27f9d5268c5413891b4a7322819ae9db Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Mon, 4 Mar 2024 15:56:19 +0100 Subject: [PATCH 12/20] smbios: rename/expose structures/bitmaps used by both legacy and modern code RH-Author: Igor Mammedov RH-MergeRequest: 230: Workaround Windows failing to find 64bit SMBIOS entry point with SeaBIOS RH-Jira: RHEL-21705 RH-Acked-by: MST RH-Acked-by: Ani Sinha RH-Commit: [10/18] 59fe438d5b7f6e584a6bb02597e4d4724fe2cece JIRA: https://issues.redhat.com/browse/RHEL-21705 As a preparation to move legacy handling into a separate file, add prefix 'smbios_' to type0/type1/have_binfile_bitmap/have_fields_bitmap and expose them in smbios.h so that they can be reused in legacy and modern code. Doing it as a separate patch to avoid rename cluttering follow-up patch which will move legacy code into a separate file.
