      mm/gup: Mark lock taken only after a successful retake · c7b6a566
      Peter Xu authored
      It's definitely incorrect to mark the lock as taken even if
      down_read_killable() failed.
      
      This wass overlooked when we switched from down_read() to
      down_read_killable() because down_read() won't fail while
      down_read_killable() could.

      mm/mempolicy: Allow lookup_node() to handle fatal signal · ba841078
      Peter Xu authored
      lookup_node() uses gup to pin the page and get node information.  It
      checks against ret>=0 assuming the page will be filled in.  However it's
      also possible that gup will return zero, for example, when the thread is
      quickly killed with a fatal signal.  Teach lookup_node() to gracefully
      return an error -EFAULT if it happens.
      
      Meanwhile, initialize "page" to NULL to avoid potential risk of
      exploiting the pointer.
      
      Fixes: 4426e945 ("mm/gup: allow VM_FAULT_RETRY for multiple times")
