From f170168b9a0b61ea1e647b082b38f605f1d3de3e Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Wed, 3 Jul 2013 15:04:58 -0700 Subject: drivers: avoid parsing names as kthread_run() format strings Calling kthread_run with a single name parameter causes it to be handled as a format string. Many callers are passing potentially dynamic string content, so use "%s" in those cases to avoid any potential accidents.
