From 432c9ed22aff641039ccd400cdabf983fabc285e Mon Sep 17 00:00:00 2001 From: Nicolas Pitre Date: Fri, 1 Oct 2010 00:10:44 -0400 Subject: vcs: invoke the vt update callback when /dev/vcs* is written to A notifier chain is called whenever the vt code modifies a terminal content, except for one case which is when the modification comes through writes to /dev/vcs* devices. Let's add the missing notifier invocation at the end of vcs_write() for that case too.
