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.
