Subject: [PATCH v3 2/9] shmem: rename functions that are memfd-related
Date:   Tue,  7 Nov 2017 13:27:53 +0100
Message-Id: <20171107122800.25517-3-marcandre.lureau@redhat.com>
In-Reply-To: <20171107122800.25517-1-marcandre.lureau@redhat.com>

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Those functions are called for memfd files, backed by shmem or
hugetlb (the next patches will handle hugetlb).
