In\nparticular, get_pages() relies on hmm_range_fault() to resolve struct\npages for the target range.\n\nAttempting to create an SVM range on such VMAs results in repeated\nget_pages() failures and can lead to an infinite loop inside a driver’s\npage‑fault handler. Prevent this by rejecting ranges on VM_IO or\nVM_PFNMAP VMAs and returning -EIO."
