Subject: [vt_console_print/cirrus_dirty_update] WARNING: at
kernel/mutex.c:858 mutex_trylock()
Greetings,
I got the below dmesg and the first bad commit is
commit 3d71c6ed43d838e593538176a9a59debe228cfb0
Author: Maarten Lankhorst <maarten.lankhorst@...onical.com>
Date: Tue Apr 2 12:33:01 2013 +0200
drm/ttm: convert to the reservation api
Now that the code is compatible in semantics, flip the switch.
Use ww_mutex instead of the homegrown implementation.
