../mm/migrate.c: In function ‘migrate_page_move_mapping’:
../mm/migrate.c:504:35: error: ‘NR_SWAPCACHE’ undeclared (first use in this function); did you mean ‘QC_SPACE’?
    __mod_lruvec_state(old_lruvec, NR_SWAPCACHE, -nr);
                                   ^~~~~~~~~~~~

../mm/memcontrol.c:1529:20: error: ‘NR_SWAPCACHE’ undeclared here (not in a function); did you mean ‘SGP_CACHE’?
  { "swapcached",   NR_SWAPCACHE   },
                    ^~~~~~~~~~~~
