softlockup: fix potential race in hung_task when resetting timeout Impact: fix potential false panic A potential race exists if sysctl_hung_task_timeout_secs is reset to 0 while inside check_hung_uniterruptible_tasks(). If check_task() is entered, a comparison with 0 will result in a false hung_task being detected. If sysctl_hung_task_panic is set, the system will panic.
