Specifically, it rechecks the source PMD status (pmd_present and pmd_special) under the page table locks, returns -EAGAIN if the PMD was concurrently cleared, properly manages page table allocation/deposit/freeing for architectures that deposit page tables, and enforces a VM_WARN_ON_ONCE assertion against writable CoW mappings. These changes alter core memory management synchronization and state handling during fork/clone operations with huge PMD / PFN mappings, which is fully reachable and worth fuzzing.)
