Subject: mm: migrate_device: use walk_page_range_vma() in migrate_vma_collect()
Date: Thu, 18 Jun 2026 17:28:45 +0800

migrate_vma_collect() uses walk_page_range() to walk the page table. 
Fortunately, migrate_vma_setup() already validates that the entire range
falls within a single VMA.

Since there is no .test_walk in migrate_vma_walk_ops and VM_PFNMAP was
filtered by migrate_vma_setup(), it's safe to replace walk_page_range()
with walk_page_range_vma() to eliminate an unnecessary find_vma() lookup.
