[PATCH v3 02/18] mm/memcg: Remove 'page' parameter to mem_cgroup_charge_statistics()
From: Matthew Wilcox (Oracle) <hidden>
Date: 2021-06-30 04:03:10
Also in:
linux-mm
Subsystem:
control group - memory resource controller (memcg), memory management, the rest · Maintainers:
Johannes Weiner, Michal Hocko, Roman Gushchin, Shakeel Butt, Andrew Morton, Linus Torvalds
The last use of 'page' was removed by commit 468c398233da ("mm:
memcontrol: switch to native NR_ANON_THPS counter"), so we can now remove
the parameter from the function.
