  commit 42c8ba5dfc0be9d646f191c744c5fa71d7f372fa
  Author: Jan Beulich <jbeulich@xxxxxxxx>
  Date:   Thu Aug 17 15:15:35 2017 +0200
  
      gnttab: don't use possibly unbounded tail calls
      
      There is no guarantee that the compiler would actually translate them
      to branches instead of calls, so only ones with a known recursion limit
      are okay:
      - __release_grant_for_copy() can call itself only once, as
        __acquire_grant_for_copy() won't permit use of multi-level transitive
        grants,
      - __acquire_grant_for_copy() is fine to call itself with the last
        argument false, as that prevents further recursion,
      - __acquire_grant_for_copy() must not call itself to recover from an
        observed change to the active entry's pin count
      
      This is part of XSA-226.
