- Part 2.5 of ARC Boot changes. Re-factor IoCreateArcNames not to use a list-entry of detected disk from pool that gets looped and de-referenced, but instead use a simple loop which calls a function that gets disk information one-by-one (IopGetDiskInformation), so that it's used on the spot instead of allocated, linked, and retrieved later.
- Inline IopAssignArcNamesToDisk to reduce some stack size abuse and too much parameter shuffling.
- Stack use is still very inefficient, will fix next.
