From: Xiaotian Feng on 10 Mar 2010 04:30 show_state will dump all tasks state, so if freezer failed to freeze any task, kernel will dump all tasks state and flood the dmesg log. This patch makes freezer only show state of tasks refusing to freeze. Signed-off-by: Xiaotian Feng <dfeng(a)redhat.com> Cc: Pavel Machek <pavel(a)ucw.cz> Cc: Rafael J.
