Subject: [PATCH 01/29] mm: shrinker: add shrinker::private_data field
From: Qi Zheng <zhengqi.arch@...edance.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.
