Subject: [PATCH v2 0/3] SLUB: improve filling cpu partial a bit in get_partial_node()
Date: Thu, 4 Apr 2024 13:58:23 +0800	[thread overview]
Message-ID: <20240404055826.1469415-1-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 remove #ifdef of
CONFIG_SLUB_CPU_PARTIAL. Please check patch 2 and patch 3.

Also add the comparison in patch 3 for when breaking from filling cpu
partial loop with ">" or ">=". For more details, please check the
patch 3 inside.

No functionality changed.

Changes in v2:
 - Refine the commit message(from Vlastimil Babka's comments).
 - Refine the check conditions of filling cpu partial(as Vlastimil Babka
   suggested).
 - drop patch 4 of v1.

v1:
