Date: Sat, 29 Nov 2014 17:45:23 +0100 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: Dave Chinner <david@...morbit.com>, xfs@....sgi.com CC: LKML <linux-kernel@...r.kernel.org>, kernel-janitors@...r.kernel.org, Julia Lawall <julia.lawall@...6.fr> Subject: [PATCH 1/1] XFS: Deletion of unnecessary checks before two function calls From: Markus Elfring <elfring@...rs.sourceforge.net> Date: Sat, 29 Nov 2014 17:40:22 +0100 The functions xfs_blkdev_put() and xfs_qm_dqrele() test whether their argument is NULL and then return immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.
