Subject: [PATCH 0/2] mm/zswap: Fixes and improves the zswap global shrinker
Date: Tue, 14 Jul 2026 16:15:08 +0800 [thread overview]
Message-ID: <20260714081510.16895-1-jiahao.kernel@gmail.com> (raw)
From: Hao Jia <jiahao1@lixiang.com>
This is the first half of the patch series[1]. The remaining part,
which covers proactive writeback, will be submitted later once the
swap tiering design is finalized.
This series fixes and improves the zswap global shrinker (shrink_worker()):
Patch 1: Fix missing global shrinker when memory cgroup is disabled.
Patch 2: Extend shrink_memcg() to support batch writeback and update its
return value semantics, thereby improving the writeback efficiency
in the shrink_worker() path.
