Subject: [PATCH 03/19] goldish_pipe: rename local pin_user_pages() routine
Date: Wed, 30 Oct 2019 15:49:14 -0700 [thread overview]
Message-ID: <20191030224930.3990755-4-jhubbard@nvidia.com> (raw)
In-Reply-To: <20191030224930.3990755-1-jhubbard@nvidia.com>
1. Avoid naming conflicts: rename local static function from
"pin_user_pages()" to "pin_goldfish_pages()".
An upcoming patch will introduce a global pin_user_pages()
function.
