Subject: [RFC PATCH 15/35] nfs: make the buf_to_pages_noslab function available to the nfs code
Date: Fri, 30 Aug 2019 22:56:03 +0000
Message-ID: <e7521ce2a3da3acde14fc54fa6ca4e4596b0e51b.1568309119.git.fllinden@amazon.com> (raw)
In-Reply-To: <cover.1568309119.git.fllinden@amazon.com>

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.
