Subject: [RFC PATCH 04/18] mm: convert to use ptep_clear() in pte_clear_not_present_full()
Date: Fri, 29 Apr 2022 21:35:38 +0800 [thread overview]
Message-ID: <20220429133552.33768-5-zhengqi.arch@bytedance.com> (raw)
In-Reply-To: <20220429133552.33768-1-zhengqi.arch@bytedance.com>
After commit 08d5b29eac7d ("mm: ptep_clear() page table helper"),
the ptep_clear() can be used to track the clearing of PTE page
table entries, but pte_clear_not_present_full() is not covered,
so also convert it to use ptep_clear(), we will need this call
in subsequent patches.
