Subject: [PATCH 0/5] Split huge PMD mapping of vmemmap pages
Date: Wed, 9 Jun 2021 20:13:05 +0800 [thread overview]
Message-ID: <20210609121310.62229-1-songmuchun@bytedance.com> (raw)
In order to reduce the difficulty of code review in series[1]. We disable
huge PMD mapping of vmemmap pages when that feature is enabled. In this
series, we do not disable huge PMD mapping of vmemmap pages anymore. We
will split huge PMD mapping when needed.
