Subject: [PATCH v2 10/13] nfs: make the buf_to_pages_noslab function available to the nfs code
Date:   Wed, 25 Mar 2020 23:10:48 +0000
Message-ID: <20200325231051.31652-11-fllinden@amazon.com>
In-Reply-To: <20200325231051.31652-1-fllinden@amazon.com>

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.
