The patch titled
Subject: mm/percpu: fix 'defined but not used' warning
has been removed from the -mm tree. Its filename was
mm-memcg-percpu-account-percpu-memory-to-memory-cgroups-fix-2.patch
This patch was dropped because it was folded into mm-memcg-percpu-account-percpu-memory-to-memory-cgroups.patch
------------------------------------------------------
From: Bixuan Cui <cuibixuan@huawei.com>
Subject: mm/percpu: fix 'defined but not used' warning
Gcc report the following warning without CONFIG_MEMCG_KMEM:
mm/percpu-internal.h:145:29: warning: 'pcpu_chunk_type' defined
but not used [-Wunused-function]
static enum pcpu_chunk_type pcpu_chunk_type(struct pcpu_chunk *chunk)
^~~~~~~~~~~~~~~
Add 'inline' to pcpu_chunk_type(),pcpu_is_memcg_chunk() and
pcpu_chunk_list() to clear warning.
