Ugh yeah I didn't realize I am moving the definitions from within an #ifdef CONFIG_MEMCG. I will just leave the definitions as-is and add a forward declaration before the definition of add_non_vmscan_reclaimed(), should also reduce the churn in the diff. Will wait for a bit before re-spinning to gather some feedback on the current version first. > > > vim +/cgroup_reclaim +549 mm/vmscan.c > > 86750830468506 Yang Shi 2021-05-04 548 > b5ead35e7e1d34 Johannes Weiner 2019-11-30 @549 static bool cgroup_reclaim(struct scan_control *sc) > 89b5fae5368f6a Johannes Weiner 2012-01-12 550 { > b5ead35e7e1d34 Johannes Weiner 2019-11-30 551 return false; > 89b5fae5368f6a Johannes Weiner 2012-01-12 552 } > 97c9341f727105 Tejun Heo 2015-05-22 553 > a579086c99ed70 Yu Zhao 2022-12-21 @554 static bool global_reclaim(struct scan_control *sc) > a579086c99ed70 Yu Zhao 2022-12-21 555 { > a579086c99ed70 Yu Zhao 2022-12-21 556 return true; > a579086c99ed70 Yu Zhao 2022-12-21 557 } > a579086c99ed70 Yu Zhao 2022-12-21 558 > > -- > 0-DAY CI Kernel Test Service > https://github.com/intel/lkp-tests
