Freezer: Only show the state of tasks refusing to freeze

4f598458 · Xiaotian Feng <[email protected]> · 2010-03-10 22:59:13 +01:00

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.
