Subject: [PATCH 50/50] nfsd4: kill write32, write64
Date: Sat, 22 Mar 2014 21:12:21 -0400 [thread overview]
Message-ID: <1395537141-10389-51-git-send-email-bfields@redhat.com> (raw)
In-Reply-To: <1395537141-10389-1-git-send-email-bfields@redhat.com>
From: "J. Bruce Fields" <bfields@redhat.com>
And switch a couple other functions from the encode(&p,...) convention
to the p = encode(p,...) convention mostly used elsewhere.
