[PATCH tip/core/rcu 2/2] virt/kvm: Replace spin_is_locked() with lockdep
From: Paul E. McKenney
Date: Wed Jan 09 2019 - 17:21:56 EST
lockdep_assert_held() is better suited to checking locking requirements,
since it only checks if the current thread holds the lock regardless of
whether someone else does. This is also a step towards possibly removing
spin_is_locked().
