Subject: [PATCH] mm: proc: remove redundant page validation of pte_page
Date: Wed, 16 Mar 2022 10:59:47 +0800 [thread overview]
Message-ID: <20220316025947.328276-1-xianting.tian@linux.alibaba.com> (raw)
pte_page() always returns a valid page, so remove the redundant
page validation, as we did in many other places.
