Subject: [dm-devel] [PATCH 01/29] mm: shrinker: add shrinker::private_data field
Date: Thu, 22 Jun 2023 08:24:26 +0000 [thread overview]
Message-ID: <20230622082454.4090236-2-qi.zheng@linux.dev> (raw)
In-Reply-To: <20230622082454.4090236-1-qi.zheng@linux.dev>
From: Qi Zheng <zhengqi.arch@bytedance.com>
To prepare for the dynamic allocation of shrinker instances
embedded in other structures, add a private_data field to
struct shrinker, so that we can use shrinker::private_data
to record and get the original embedded structure.
