Subject: liblockdep: Stub task_struct::state
Forwarded: https://lore.kernel.org/lkml/20180828233752.GG18030@decadent.org.uk/T/#u

lockdep_print_held_locks() now checks task_struct::state.  Define it
so that all tasks are assumed to be running, since we have no
reasonble way to tell in user-space.

Fixes: 8cc05c71ba5f ("locking/lockdep: Move sanity check to inside ...")
