Subject: [PATCH-tip 0/5] locking/locktorture: Fix locktorture ww_mutex test problems

This is a follow-up patch series for the previous patchset on fixing
locktorture ww_mutex test problem [1]. The first 3 patches of that
series were merged into tip. It turns out that the last one of the
three wasn't quite right. So this patch series revert the last patch.

The rests of the patch series fix the ww_mutex testing problem in
locktorture as well as removing the DEFINE_WW_MUTEX() macro from
include/linux/ww_mutex.h.

  locking/ww_mutex: Revert "Treat ww_mutex_lock() like a trylock"

  locking/locktorture: Pass thread id to lock/unlock functions
  locking/locktorture: locking/locktorture: Fix incorrect use of
