Subject: [PATCH v2 07/13] mm/gup: remove locked being NULL from faultin_vma_page_range()
Date: Tue, 24 Jan 2023 16:34:28 -0400 [thread overview]
Message-ID: <7-v2-987e91b59705+36b-gup_tidy_jgg@nvidia.com> (raw)
In-Reply-To: <0-v2-987e91b59705+36b-gup_tidy_jgg@nvidia.com>
The only caller of this function always passes in a non-NULL locked,
so just remove this obsolete comment.
