From cb2f6e00200df2c15a22f54196879c523fa610da Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Mon, 7 May 2018 07:58:05 +0200 Subject: [PATCH 09/13] pc-bios/s390-ccw: rename MAX_TABLE_ENTRIES to MAX_BOOT_ENTRIES RH-Author: Thomas Huth Message-id: <1525679888-9234-4-git-send-email-thuth@redhat.com> Patchwork-id: 80052 O-Subject: [RHEL-7.6 qemu-kvm-ma PATCH 3/6] pc-bios/s390-ccw: rename MAX_TABLE_ENTRIES to MAX_BOOT_ENTRIES Bugzilla: 1523857 RH-Acked-by: David Hildenbrand RH-Acked-by: Cornelia Huck RH-Acked-by: Laszlo Ersek From: Collin Walling The MAX_TABLE_ENTRIES constant has a name that is too generic. As we want to declare a limit for boot menu entries, let's rename it to a more fitting MAX_BOOT_ENTRIES and set its value to 31 (30 boot entries and 1 default entry). Also we move it from bootmap.h to s390-ccw.h to make it available for menu.c in a later patch.
