Subject: [Qemu-devel] [PULL (resend, rebase) 5/5] virtio-serial: Don't clear ->have_data() pointer after unplug
Date: Thu, 10 Mar 2011 11:39:19 +0530	[thread overview]
Message-ID: <0f35b89ae35e35afa8499f8016900ace82bc86a5.1299737220.git.amit.shah@redhat.com> (raw)
In-Reply-To: <cover.1299737219.git.amit.shah@redhat.com>
In-Reply-To: <cover.1299737219.git.amit.shah@redhat.com>

After a port unplug operation, the port->info->have_data() pointer was
set to NULL.  The problem is, the ->info struct is shared by all ports,
effectively disabling writes to other ports.
