Message-Id: <1363675621-31186-2-git-send-email-haodong@linux.vnet.ibm.com> Date: Tue, 19 Mar 2013 14:47:00 +0800 From: Dong Hao <haodong@...ux.vnet.ibm.com> To: gregkh@...uxfoundation.org Cc: xiaoguangrong@...ux.vnet.ibm.com, shangw@...ux.vnet.ibm.com, weiyang@...ux.vnet.ibm.com, linux-kernel@...r.kernel.org, Dong Hao <haodong@...ux.vnet.ibm.com> Subject: [PATCH 2/3] lib/kobject: Panic when kobj or ktype is not properly assigned From: Dong Hao <haodong@...ux.vnet.ibm.com> kobj and ktype are two important attributes which will be used after kobject_init(), and (!kobj)|(!ktype) may cause FS corruption which could not be recovered. Panic instead of dump_stack() when neither kobj nor ktype is properly assigned to detect the bug early.
