Subject: [PATCH 02/15] btrfs: Make WARN_ON in a canonical form
Date: Wed, 30 Jan 2019 16:50:49 +0200 [thread overview]
Message-ID: <20190130145102.4708-3-nborisov@suse.com> (raw)
In-Reply-To: <20190130145102.4708-1-nborisov@suse.com>
There is no point in using a construct like 'if (!condition)
WARN_ON(1)'. Use WARN_ON(!condition) directly. No functional changes.
