Subject: [PATCH 10/17] AFS: afs_send_empty_reply() doesn't require an iovec array
Date: Sat, 11 Apr 2015 22:18:21 +0100	[thread overview]
Message-ID: <1428787108-13650-10-git-send-email-viro@ZenIV.linux.org.uk> (raw)
In-Reply-To: <20150411211742.GJ889@ZenIV.linux.org.uk>

From: David Howells <dhowells@redhat.com>

afs_send_empty_reply() doesn't require an iovec array with which to initialise
the msghdr, but can pass NULL instead.
