Subject: [PATCH 2/6] ext4: remove useless BUG_ON in ext4_ext_insert_extent
Date: Thu, 17 Nov 2011 10:03:21 +0800 [thread overview]
Message-ID: <1321495405-9583-2-git-send-email-xiaoqiangnk@gmail.com> (raw)
In-Reply-To: <1321495405-9583-1-git-send-email-xiaoqiangnk@gmail.com>
npath is set to NULL and is not set again before BUG_ON, so
the BUG_ON is useless.
