From a17b485aae3effe2f35345dc7af4ed2070a2d949 Mon Sep 17 00:00:00 2001 From: piaojun Date: Thu, 5 Apr 2018 16:18:52 -0700 Subject: ocfs2: remove unnecessary null pointer check before kmem_cache_destroy() As kmem_cache_destroy() already handles null pointers, so we can remove the conditional test entirely.
