The patch titled
Subject: mm: memcg: remove obsolete memcg_has_children()
has been removed from the -mm tree. Its filename was
mm-memcg-remove-obsolete-memcg_has_children.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Lukas Bulwahn <lukas.bulwahn@gmail.com>
Subject: mm: memcg: remove obsolete memcg_has_children()
Commit 2ef1bf118c40 ("mm: memcg: deprecate the non-hierarchical mode")
removed the only use of memcg_has_children() in
mem_cgroup_hierarchy_write() as part of the feature deprecation.
Hence, since then, make CC=clang W=1 warns:
mm/memcontrol.c:3421:20:
warning: unused function 'memcg_has_children' [-Wunused-function]
Simply remove this obsolete unused function.
