Subject: [PATCH 23/27] NFS: Fix memory leak [try #2]
Date: Wed, 23 Jan 2008 17:22:41 +0000	[thread overview]
Message-ID: <20080123172241.11107.75955.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <20080123172038.11107.86025.stgit@warthog.procyon.org.uk>

Fix a memory leak whereby multiple clientaddr=xxx mount options just overwrite
the duplicated client_address option pointer, without freeing the old memory.

Signed-off-by: David Howells <dhowells@redhat.com>
