From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx> Date: Sat, 21 Feb 2015 17:40:57 +0100 The functions kfree(), ocfs2_free_path() and __ocfs2_free_slot_info() test whether their argument is NULL and then return immediately. Thus the test around their calls is not needed. This issue was detected by using the Coccinelle software.
