Daniel P. Berrangé 9a23075cef chardev/char-socket: skip automatic zero-init of large array ... The 'tcp_chr_read' method has a 4k byte array used for copying data between the socket and device. Skip the automatic zero-init of this array to eliminate the performance overhead in the I/O hot path. The 'buf' array will be fully initialized when reading data off the network socket.
