Subject: [PATCH] mm/mempolicy: use helper range_in_vma() in queue_pages_test_walk()
Date: Sat, 30 Jan 2021 04:13:52 -0500 [thread overview]
Message-ID: <20210130091352.20220-1-linmiaohe@huawei.com> (raw)
The helper range_in_vma() is introduced via commit 017b1660df89 ("mm:
migration: fix migration of huge PMD shared pages"). But we forgot to
use it in queue_pages_test_walk().
