Subject: [PATCH v3 3/4] mm: migrate: Fix the incorrect function name in comments
Date: Sat, 21 Aug 2021 15:54:58 +0800	[thread overview]
Message-ID: <5b824bad6183259c916ae6cf42f81d14c6118b06.1629447552.git.baolin.wang@linux.alibaba.com> (raw)

In-Reply-To: <cover.1629447552.git.baolin.wang@linux.alibaba.com>

since commit a98a2f0c8ce1 ("mm/rmap: split migration into its own function"),
the migration ptes establishment has been split into a separate
try_to_migrate() function, thus update the related comments.
