Subject: [PATCH 0/4] SLUB: improve filling cpu partial a bit in get_partial_node()
Date: Sun, 31 Mar 2024 10:19:22 +0800	[thread overview]
Message-ID: <20240331021926.2732572-1-xiongwei.song@windriver.com> (raw)

From: Xiongwei Song <xiongwei.song@windriver.com>

This series is to remove the unnecessary check for filling cpu partial
and improve the readability.

Introduce slub_get_cpu_partial() and dummy function to prevent compiler
warning with CONFIG_SLUB_CPU_PARTIAL disabled. This is done in patch 2.
Use the helper in patch 3 and 4.

No functionality changed.

Actually, the series is the improvement of patch below:
