We should also ensure that vaddr >= vm_start, > find_vma() guarantees "vaddr < vm_end" only. > > 2. After the prevous changes, register_for_each_vma() is the only > reason why vma_address() has to return loff_t, all other users > know that we have the valid mapping at this offset and thus the > overflow is not possible. > > Change the code to use vaddr_to_offset() instead, imho this looks > more clean/understandable and now we can change vma_address(). > > 3. While at it, remove the unnecessary type-cast. > > Signed-off-by: Oleg Nesterov <o...@redhat.com>
