File 0001-disk-Optimize-disk-iteration-by-moving-memdisk-to-th.patch of Package grub2
From 5846e14a4dbf0c73969a32625d841e4f842ccdea Mon Sep 17 00:00:00 2001 From: Michael Chang <mchang@suse.com> Date: Wed, 31 Jan 2024 18:44:27 +0800 Subject: [PATCH] disk: Optimize disk iteration by moving memdisk to the end When performing file or UUID-based searches, prioritize returning operating system disk devices over the memdisk. The memdisk, typically used for internal grub data, is moved to the last position in the search order. This improves search efficiency and prevents potential unexpected results.
