  In upstream stable 4.4.218, the following patch brings back kref_read()

  == Fix ==
  
  Disable the internal re-implementation of kref_read() for kernels
  including upstream stable 4.4.218.
  
  == Testcase ==
  
  Running dkms build for various kernel versions (tested with
  Ubuntu-4.4.0-178 and Ubuntu-4.4.0-179). With -178 building currently
  succeeds, with -179 it fails.
  
  == Risk of Regression ==
  
  Low, internal implementation which was backported from kernel 4.11 gets
  replaced by the kernel function.
