Subject: [PATCH v2 3/7] ksm: remove redundant declarations in ksm.h
Date: Wed, 31 Aug 2022 11:19:47 +0800 [thread overview]
Message-ID: <20220831031951.43152-4-zhengqi.arch@bytedance.com> (raw)
In-Reply-To: <20220831031951.43152-1-zhengqi.arch@bytedance.com>
Currently, for struct stable_node, no one uses it in both the
include/linux/ksm.h file and the file that contains it. For
struct mem_cgroup, it's also not used in ksm.h. So they're all
redundant, just remove them.
