The patch titled Subject: memcg: writeback: use memcg->cgwb_list directly has been removed from the -mm tree. Its filename was memcg-writeback-use-memcg-cgwb_list-directly.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Wang Long <wanglong19@xxxxxxxxxxx> Subject: memcg: writeback: use memcg->cgwb_list directly mem_cgroup_cgwb_list is a very simple wrapper and it will never be used outside of code under CONFIG_CGROUP_WRITEBACK. so use memcg->cgwb_list directly.
