If this patch meets the merge guidelines for a bugfix, it should be merged into Linus's tree before the next major kernel release. If not, it will be merged into Linus's tree during the next merge window. Either way, you will probably be copied on the patch when it gets sent to Linus for merging so that others can see what is happening in kernel development. If you have any questions about this process, please let me know. >>From nico@fluxnic.net Tue Oct 5 15:58:16 2010 Date: Fri, 01 Oct 2010 00:10:44 -0400 (EDT) From: Nicolas Pitre To: lkml Cc: Greg Kroah-Hartman , Andrew Morton Subject: vcs: invoke the vt update callback when /dev/vcs* is written to Message-id: 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.
