Subject: [PATCH v2 0/3] SLUB: improve filling cpu partial a bit in get_partial_node()
From: Xiongwei Song <xiongwei.song@...driver.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:
