From 72865d92300a6ad20a8851887aeac4f41fd2c579 Mon Sep 17 00:00:00 2001 From: Joseph Qi Date: Thu, 14 Jan 2016 15:17:27 -0800 Subject: [PATCH] ocfs2: clean up redundant NULL check before iput Since iput will take care the NULL check itself, NULL check before calling it is redundant. So clean them up.
