Peter Zijlstra 28eab3db72 locking/lockdep: Add nest_lock integrity test ... [ Upstream commit 7fb4a2cea6 ] Boqun reported that hlock->references can overflow. Add a debug test for that to generate a clear error when this happens. Without this, lockdep is likely to report a mysterious failure on unlock.
