[merged mm-stable] memcg-expose-mem_cgroup_ino-and-mem_cgroup_get_from_ino-unconditionally.patch removed from -mm tree

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

The quilt patch titled
     Subject: memcg: expose mem_cgroup_ino() and mem_cgroup_get_from_ino() unconditionally
has been removed from the -mm tree.  Its filename was
     memcg-expose-mem_cgroup_ino-and-mem_cgroup_get_from_ino-unconditionally.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: memcg: expose mem_cgroup_ino() and mem_cgroup_get_from_ino() unconditionally
Date: Thu, 25 Dec 2025 15:21:10 -0800

Remove the CONFIG_SHRINKER_DEBUG guards around mem_cgroup_ino() and
mem_cgroup_get_from_ino().  These APIs provide a way to get a memcg's
cgroup inode number and to look up a memcg from an inode number
respectively.

Making these functions unconditionally available allows other in-kernel
users to leverage them without requiring CONFIG_SHRINKER_DEBUG to be
enabled.

No functional change for existing users.
