Tejun Heo 88f1c87de1 locking/lockdep: Avoid triggering hardlockup from debug_show_all_locks() ... debug_show_all_locks() iterates all tasks and print held locks whole holding tasklist_lock. This can take a while on a slow console device and may end up triggering NMI hardlockup detector if someone else ends up waiting for tasklist_lock. Touch the NMI watchdog while printing the held locks to avoid spuriously triggering the hardlockup detector.
