Subject: [PATCH] drm/i915: redefine WARN_ON_ONCE to include the condition
Date: Thu, 12 Mar 2015 13:01:12 +0200 [thread overview]
Message-ID: <1426158072-19331-1-git-send-email-jani.nikula@intel.com> (raw)
Same as
commit c883ef1b1c998d2d66866772fd0fc34afa45641e
Author: Mika Kuoppala <miku@iki.fi>
Date: Tue Oct 28 17:32:30 2014 +0200
drm/i915: Redefine WARN_ON to include the condition
but for WARN_ON_ONCE. Since the kernel WARN_ON_ONCE actually picks up
*our* version of WARN_ON, we end up with messages like
[ 838.285319] WARN_ON(!__warned)
which are not that helpful.
