[Andrew Morton <akpm@linux-foundation.org>]

The quilt patch titled
     Subject: mm: memcg: put struct task_struct::memcg_in_oom under CONFIG_MEMCG_V1
has been removed from the -mm tree.  Its filename was
     mm-memcg-put-struct-task_struct-memcg_in_oom-under-config_memcg_v1.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: mm: memcg: put struct task_struct::memcg_in_oom under CONFIG_MEMCG_V1
Date: Fri, 28 Jun 2024 21:03:16 +0000

The memcg_in_oom field of the struct task_struct is not used by the cgroup
v2's memory controller, so it can be happily compiled out if
CONFIG_MEMCG_V1 is not set.
