Subject: [PATCH 10/13] nfs: make the buf_to_pages_noslab function available to the nfs code
Date:   Wed, 11 Mar 2020 19:56:10 +0000
Message-ID: <20200311195613.26108-11-fllinden@amazon.com>
In-Reply-To: <20200311195613.26108-1-fllinden@amazon.com>

Content-Type: text/plain
Sender: linux-nfs-owner@vger.kernel.org
Precedence: bulk

Make the buf_to_pages_noslab function available to the rest of the NFS
code. Rename it to nfs4_buf_to_pages_noslab to be consistent.

This will be used later in the NFSv4.2 xattr code.
