From 13cb076d3057e0c4b26acb0ee5e5d6ea9b5131c0 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Tue, 2 Dec 2014 11:40:33 +0100 Subject: [PATCH] lustre: Deletion of unnecessary checks before three function calls The functions free_ll_remote_perm(), free_rmtperm_hash() and iput() 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.
