Subject: [PATCH 3/4] mm: drop unused argument of zap_page_range()
Date: Mon, 19 Dec 2016 20:17:21 +0300 [thread overview]
Message-ID: <20161219171722.77995-3-kirill.shutemov@linux.intel.com> (raw)
In-Reply-To: <20161219171722.77995-1-kirill.shutemov@linux.intel.com>
There's no users of zap_page_range() who wants non-NULL 'details'.
Let's drop it.
