From 66db6cfd49825f4e3462ceee3bcbb292d57da6fb Mon Sep 17 00:00:00 2001 From: Joseph Qi Date: Thu, 22 May 2014 11:54:22 -0700 Subject: ocfs2: fix double kmem_cache_destroy in dlm_init In dlm_init, if create dlm_lockname_cache failed in dlm_init_master_caches, it will destroy dlm_lockres_cache which created before twice. And this will cause system die when loading modules.
