Re: [libvirt] [PATCH] char: drop data written to a disconnected pty

Either way, when a pty is disconnected data will get dropped, whether by the pty backend (as proposed) or by the serial port device or other frontend (as currently). The only difference from a user's perspective is whether the dropped data gets written to the log file, which is the main motivation for this change. The backward compatibility concern would be an existing application that relies on data not being logged when the pty is disconnected.
