The BPF program accesses only the\nsnapshot.\n\nThe verifier only trusts vm_mm and vm_file pointers (see\nBTF_TYPE_SAFE_TRUSTED_OR_NULL in verifier.c). vm_file is reference-\ncounted with get_file() under the lock and released via fput() on the\nnext iteration or in _destroy(). vm_mm is already correct because\nlock_vma_under_rcu() verifies vma->vm_mm == mm.
