Subject: [PATCH] mm: remove obsolete comment in do_fault_around()
Date: Sat, 16 Jul 2022 16:03:59 +0800 [thread overview]
Message-ID: <20220716080359.38791-1-linmiaohe@huawei.com> (raw)
Since commit 7267ec008b5c ("mm: postpone page table allocation until we
have page to map"), do_fault_around is not called with page table lock
held. Cleanup the corresponding comments.
