Change call_usermodehelper_exec() to\ncheck sub_info-\u003epath !\u003d NULL to avoid the crash.\n\nThis is the minimal fix, todo:\n\n - perhaps we should change argv_split() to return NULL or change the\n   callers.\n\n - kill or justify -\u003epath[0] check\n\n - narrow the scope of helper_lock()\n\nSigned-off-by: Oleg Nesterov \u003coleg@redhat.com\u003e\nAcked-By: Lucas De Marchi \u003clucas.demarchi@intel.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n\n",
