From 22555c177977b1010885a7a5107e338b179420e2 Mon Sep 17 00:00:00 2001 From: Nicolas Pitre Date: Tue, 8 Jan 2019 22:55:00 -0500 Subject: [PATCH] vt: always call notifier with the console lock held commit 7e1d226345f89ad5d0216a9092c81386c89b4983 upstream. Every invocation of notify_write() and notify_update() is performed under the console lock, except for one case. Let's fix that.
