Subject: [patch 02/55] mm: percpu: add pcpu_fc_cpu_to_node_fn_t typedef
Date: Wed, 19 Jan 2022 18:07:45 -0800	[thread overview]
Message-ID: <20220120020745.FuVQeKWep%akpm@linux-foundation.org> (raw)
In-Reply-To: <20220119180714.9e187ce100e4510de3cd9f7d@linux-foundation.org>

From: Kefeng Wang <wangkefeng.wang@huawei.com>
Subject: mm: percpu: add pcpu_fc_cpu_to_node_fn_t typedef

Add pcpu_fc_cpu_to_node_fn_t and pass it into pcpu_fc_alloc_fn_t, pcpu
first chunk allocation will call it to alloc memblock on the corresponding
node by it, this is prepare for the next patch.
