From mboxrd@z Thu Jan 1 00:00:00 1970 From: Dan Carpenter Date: Tue, 24 Jan 2012 08:41:09 +0000 Subject: [patch] ext4: remove an unneeded NULL check Message-Id: <20120124084109.GC29097@elgon.mountain> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: Theodore Ts'o Cc: Andreas Dilger , linux-ext4@vger.kernel.org, kernel-janitors@vger.kernel.org We dereference "bh" unconditionally a couple lines down to find "by->b_size". This function is never called with a NULL "bh" so I have removed the check.
