Subject: [PATCH 1/2] cgroup/cpuset: Remove cpuset_do_slab_mem_spread()
Date: Thu, 29 Feb 2024 22:20:06 +0800 [thread overview]
Message-ID: <20240229142007.1278610-1-xiongwei.song@windriver.com> (raw)
The SLAB allocator has been removed sine 6.8-rc1 [1], so there is no user
with SLAB_MEM_SPREAD and cpuset_do_slab_mem_spread(). Then SLAB_MEM_SPREAD
is marked as unused by [2]. Here we can remove
cpuset_do_slab_mem_spread(). For more details, please check [3].
